Anyone out there remember a movie from the (early) eighties (I think) about a guy who accidentally designs a pair of jeans with two holes cut out where the back pockets should be? The ass-revealing jeans start a fashion craze; everybody is wearing them, and wacky hijinx ensue from there.
Ring any bells? I've got 3-1 odds Mr. Ninja comes through. I remember watching it on HBO like fifty times w/ my brothers but I can't remember what it was called.
