A man goes to the Bakers and asks :- ''Do you have any yellow bread ?'' ''No,only green'' says the Baker. ''Well give me a blue one then, I'm riding the bike.''
This joke started doing the rounds in university rag mags circa 1980.(Unless anyone knows of an earlier occurrence)
The whole point of it is, it is complete nonsense.
Incidentally, the original version(s) involved him asking for a small loaf, to be told they only had large ones, or sometimes vice versa.
Dassie, just noticed something.
How do you get blue by mixing yellow and green ?
Even if you are talking about light, you will end up with something greenish/yellow
I must admit it cracked me up when I heard it. I think it was all in the delivery though as I've tried to repeat it and I'm just not cute enough to pull it off!
