Twarnold Twinzenegger and Twinny DeVito play twins. One of them absconded with a German scientist to a remote Pacific island, but remained a virgin, while the other banged a nun. There's lots of twinning around, rules, and a whole lotta chains. You don't try to renegotiate with old beetroot, and you don't try to shoot Kelly Preston in the arm. 1988's Twins.
