@wandeljw,
An oldie from Lord Ellpus:
Man walks into a bar and orders a pint and a packet of peanuts.
He pays, takes the pint and downs it in one, puts the packet of peanuts on his head and walks out.
Barman looks quizzical.
Next night the same thing...puts the peanuts on his head and walks out.
Third night and the barman's waiting for him, curious as hell.
"Pint of beer and a packet of peanuts, please"
The barman pours the pint, goes to get the peanuts and finds they've sold out. He looks at the guy and says"We've only got cashews"
"OK" says the guy "They'll do"
He drinks the pint, puts the cashews on his head and goes to walk out.
"Wait a minute" says the barman "You have to tell me, as it's been driving me mad. Why have you put that packet of cashews on your head?"
"'Cos you've got no peanuts" says the man.
