Funniest moment/scene on TVD?

Oh, without a doubt, the bedroom scene in Under Control in season one, when it begins with Elena greeting Damon at the door, "Good, you're here." Damon says, "You ask, I come. I'm easy like that."
"NO, ELENA, I WON'T GO TO YOUR BEDROOM WITH YOU!" shouts it loud enough for Jeremy to hear. She has to pull him to the stairs as he is laughing.

When he opens her bedroom door, "Just like I remembered."

This whole scene is filled with flirtation on Damon's part (all of it with a hint of sexual innuendo) as he flops onto her bed, opens her underwear drawer and examines a bra. I laugh so much when she has to rip it out of his hands to put it back. Then he steals a picture. Damon invades her personal space and gets close enough to make her gulp. This whole episode is one of my favorites between them.

I need to have more scenes between them like this in season 3.

i think it if funny on 2x1 when...
Stefan: What happened when katherine showed up tonight?
(Damon shrugges)
Damon: Its a risk another frown line encroaching on a very crowded forehead, we... kissed.
Elena: And you thought it was me?
Stefan: What do you mean you kissed?
Damon: Well you know when two lips pucker and go.. (kissy noises)
(Stefan rushes damon)
Damon: Dont be obvious stefan
Haha love that scene i think it is hillarious!!!

When stefan was writing in his diary and Damon walks in
and says "dear diary, today a chipmunk asked me my name.
I told him it was joe. That lie will haunt me forever."
lol can't remember what season and episode soz :)

For me it's any scene where Bonnie and Damon are bickering.
