I remember three jokes from Packet of Three. I'm possibly the show's biggest fan, being as I thought it was 'ok'
1. Jenny Eclair "I've made a pair of knickers out of origami swans; but I think I've got them on inside out"
Skinner- "that's it Jen, keep your pecker up"
2. Frank Skinner's character lists a series of her faults to Jenny Eclair's character, ending with, "... and you smell when you've got your period;" she knees him in the groin and he doubles over saying something like "thanks, I deserved that"
3. A Henry Normal joke. Forget the set-up, but the punchline was "cash and karaoke!"
