This is one is easy..i can choose in a glimpse..
My vote goes to
Ohno Satoshi and
Aiba Masaki..
This 2 persons obviously the funniest members out of all but in different kind of way:
Ohno is type of blurry guy and spaced out a lot in variety shows but u might be having a heart attack whenever he speaks something. His face expression is definitely priceless. Doesn't talk a lot but once he open his mouth, you'll be burst into laugh with his innocent face and straightforwardness. I died with his famous 'umai' words.
Aiba is type of guy who talked a lot, vice versa with Ohno. His talents is definitely in hosting a variety show. He always curious about something and came up with his Baka idea and eventho the other members (except for Ohno) complaints about his idea a lot, they will ending up doing together with him. He is indeed the mood maker in the group.
Can i vote both of them?..(
Sho,
Nino and
Jun can be funny sometimes, esp when all 5 of them together)
