He has a lot of hilarious quotes
"Why are you looking at my tail Yamcha? I won't turn into a great Ape. Relax, will you!?"
And telling Tien to fuse with Yamcha is also hilarious as fuck lmfao.
Also this is the funniest one:
Piccolo when Gohan is about to get eliminated: "It's OK Gohan I have stretchy arms!"
Piccolo when he is about to get eliminated: "Oh no if only I had something like stretchy arms to get me back up on the ring"
