cone but he is basicaly the comic relief of the anime
Ichigo.
He'll be all kickass one minute... and another trying to be a cool laid-back teen ... and then so frustrated/annoyed/confused the next that he's going nuts. A lot funnier than the characters designed to be more comic relief.
Rukia's gigai replacement
madarame ikkaku especially when he's with keigo's sister!^^ hahahaha how can the girl fall for him? he wears make up, and he's bald! lol!XD
Edit: i forgot it was nel tu! she's so funny, especially when she says "itsugo!!!"
yachiru too! he keeps calling people by different nicknames...
I think everybody makes me laugh at some point but i think Ichigo is the funniest =P
it has to be kon or keigo asano wen he tells his lame stories^.^
Kon or Keigo.
Or even Hanataro or Ganju.
