great effort, good production - I am a fan of musical comedy.... personally I think the crapping song needed more build up to the punchline, some clever lyrical play in there, but does make for quite uncomfortable listening start to finish, you need to play with the shockfactor a bit more...
it reminded me a bit of jizz in my pants from lonely island, this is obviously a big budget production, but the writing is impressive in its build up/pay off... if you haven't seen it, worth checking out...
