I feel like I should be saying no, but then again, I wouldn't exactly be very honest saying that...

Has anyone here ever had the uncontrollable urge to scream "THIS IS SPARTA!!" and promptly run out the window of 3+ story tower? In the most ridiculous way possible??

Yes, as long as I'm bringing the bad guys with me.

This actually happened on a popular D&D livestream (Nights of Eveningstar ((they did not scream "SPARTA" though) episode 36 Window Pains).

Has anyone had the uncontrolabe urge to kill your DM's favorite NPC? (:No one will ever know:)

Has anyone ever had the urge to just set FIRE to your dm's plans by going wildly off track just to see the look on your face

Has anyone ever had the urge to... nevermind.

Has anyone ever had the nigh-uncontrollable urge to ask the DM "Can I have a siege tower as a pet??", just to see the look on the DM’s face?

Basically this but with 1 to 3 ballistae on top, and maybe a trebuchet or similar device: 

Have you ever murdered hundreds of innocents and fed them to the hill giant so you don't have to fight him, just to see the look on your DM's face?

No. Have you ever said "I would like to seduce the dragon" without knowing what it meant, just to see the look on your DM's face?

(I have)

Have you ever auditioned to become the best musician/music act in the world and judged by a shadow dragon who's only meaning to its immortal life is to guide the person with the most musical potential to fame and glory, but said "Can I use a synth?" (when there's absolutely no electricity at all) just to see the look on your DM's face?

I did. I did great, actually.

Has anyone ever had the nigh-uncontrollable urge to do a William Shatner impression as their character voice, just to see the look on their DM’s face?

Has anyone ever had the nigh-uncontrollable urge to make a party entirely out of bards just to see the look on your DM’s face?

Comment 500- I’d say that’s an achievement

Yes, I have actually. 😂😂

have you ever played a sorcerer, and played a 9th level fireball directly on yourself as you ran towards a large group, saying "WITNESS ME!", just to see the look on your DM's face?

(i made a group of draconic Bards one time named Imagine Humans)

Has anyone ever had the nigh-uncontrollable urge to use a potato for their mini, just to see the look on your DM’s face?

Has anyone ever had the nigh-uncontrollable urge to scream “GYRATING KOALAS!” as a battle cry just to see the look on your DM’s face?

 Not that exact battle cry, but I have had the urge to say similarly crazy ones.

Has anyone ever had the nigh-uncontrollable urge to make a pikachu homebrew character just to see the look on your DM’s face?

no, I haven't, but that's mainly because I hate pikachu.
I resent it to the point that I would be 120% willing to take one and do something to it to show just how much I despise pikachu (probably involving fire because arson good and arson yes)

I'd go into huge amounts of why I think pikachu is garbage and why i think there are hundreds of options that are better, such as Aegislash, Umbreon, Greninja, Alolan Raichu (who is way better than non-Alolan Raichu), just about every Legendary and Mythical Pokemon in existence (Mewtwo kinda mid in my opinion), Absol (especially with the ability Super Luck and a critical-hit-chance-raising item), Garchomp, Lucario, etc.
To be fair, the only pikachu I respect, have respected, and will ever respect is Detective Pikachu because he is actually pretty intelligent and intelligent to have a reference made about him in Pokemon Sword and Shield, have a pretty good game made about him, and a pretty good movie made about the game that was about him.
Ash and his pikachu are both idiots in my opinion. Ash is also fairly heartless, too, since he leaves all of his friends behind and moves onto another region without ever thinking about those friends ever again, and the same goes for his Pokemon.

anyway, has anyone ever had the nigh-uncontrollable urge to ask the DM "Can I have first dibs on that glowing green patterned circle on the second floor and summon the Ancient One via mispronouncing Latin sentences" just to see the look on your DM's face?
Basically this:

I also asked this to my Latin teacher a month or 2 ago, but in a slightly different way: "May I have your permission to summon the Ancient One after school?" 
She said "what? no." and I still have no idea why she would say such a thing...
I mean, I don't see an issue with it (now that I said that, maybe THAT'S the issue...)

I told the DM I would be playing a character that would only canonically speak Latin (so whenever I asked to do something, I did it in Latin). At one point, I asked to release a dragon, and no one could understand what I was doing. I eventually did it, and we all died. End of campaign.

As a DM... I have been given many thoughts to think. I want to make a forum thread like this but for DMs now.

Has anyone ever had the nigh-uncontrollable urge to make a character that was three kobolds in a trench coat pretending to be one big dragonborn, just to see the look on your DMs face? 

I have. It was the best character I've ever made to this day.

I totally have. last campaign I dm'd, i made the 3 kobolds in a trench coat npc, and the players rolled low perception to see they were obviously kobolds
