Auf Wiedersehen, Pet, Series 3

[Oz and Moxey are messing about on a bike, Barry stressed about his polygraph test]

Moxey:
Some exercise wouldn't do you any harm.

Barry:
You wouldn't get me on a bike, that's the last form of exercise I'd take. Cycling damages your sexual organs.

Oz:
Bollocks!

Barry:
Precisely, no I read this research report. Right, they use ultrasound scans to examine the testicles of 45 mountain bikers and they compared them with 39 sets of testicles of non-riders, and all but two of the cyclists had scrrrrotal abnormalities.

Moxey:
He knows a lot of stuff, Barry.

Oz:
Aye, all of it useless. [Moxey and Oz simultaneously feel their testicles]
