Aeolus, your joke is lame, but I get it.
I do not get the glass eye joke by WER. Perhaps explain it to me in PM?
Here's one of my own.
Man and wife at a fete, right? And there's a guy in a plane giving rides for a tenner. He gives rides to about five people, then notices the man and wife, who were watching. So the guy says, 'I've noticed you watching me. How about I give you a ride for free? As long as you stay quiet.'
Man and wife think this is a good deal. So they strap themselves in, and do the ride. Later, on the ground, the plane guy says 'You were very quiet back there.'
Man says 'Yeah I know. Almost said something there when my wife fell out.'
