Humor is subjective
If you don't find penis jokes and similar forms of humor to be funny, then stop leaving negative feedback on movies that you shouldn't have watched in the first place. I mean for god's sakes it's got DICKS in the title. If you don't like dick jokes, then FUCK OFF; don't watch it in the first place!
Bloody reviewers...
On a side note, why is this your last sprite movie? they're funy every once in a while; don't put the kaibosh on yourself just yet, and I might show you my dirty slut jutsu :D
