Paddy was telling Mick about taking his first parachute jump.
"When I got to the door I couldn't jump. The 6'7" man mountain black instructor unzipped his fly and dropped out his 14 incher and said 'If you don't jump you're gonna get this baby right up your arse'.".
Mick says, "Did you jump?".
Paddy says, "A bit, when it first went in".
