What about:
"Joe, go back in there and get me an M-azing bar."
*A few moments later, after Joe is embarrased from having to go back in a few seconds after he left*
"So, are they any good?"
"I don't know. I just wanted one because you had one"
How about
"Joe and Matt, you guys are idiots" *whacks both them in the back of the head*
Don't forget that I also threw a water bottle at him.
How about:
"It's merely a flesh wound!!"
Or one of the other million awesome Monty Python quotes?
Oh my God! DId you see that bear up there Matt?
Yea that bear was HUGE!!!
(Scared little kids run away from the woods.
beware of the evil Joepire!
