I also am for the laughing meter idea, it would be fun to do, a little extra work, but definitely worth it. I also like the penis counter, for how many times penis is either referenced or said directly.
I omly thought of literal references to penis, but your idea is better. The only episode where you really hear the word penis a lot is in episode 3.
Oh, and if there were a Dub Piece video game, my first thought, like pretty much everyone else's, would to just do a paody of the average anime fighting game, similar to how Dub Piece is a parody in and of itself. Here's my list list of playable characters, based on the first season, with some attacks ripped from the episodes that would be good for the game. If I missed anyone, it's probably because I forgot their name or if they were even in the episode:
Luffy (Attacks: Laffy Taffy Superball Wonder-Force Explosion, Laffy Taffy Grab-Your-Hand Attack)
Zoro
Nami
Ussop
Sanji (Attacks: Hamburger Helper, Clam Bake Clothesline)
Vivi
Crocodile
Mr. 2 Bon Clay (Attack: Bitch Slap)
Tony Chopper
Captain Foxy
Django
Captain Kuro
Nico Robin (Attack: Multiple Arms and Legs and Shit)
Chef Zeff (Attack: Seismic Toss)
Don Kreig (Attack: Poison Suction Cups)
Arlong (Attack: turns into Al Kahn)
Hachi
the fillain whose name I can't remember (Attack: Long Finger Nails)
Helper Characters
Veggie Pirates
Carue
Well, that's all I got for now.
