I just found some amusing questions on someone else's blog and thought I would steal some of them.
If money doesn't grow on trees then why do banks have branches?
What disease did cured ham actually have?
If a 999 operator has a heart attack, who do they call?
Who was the first person to look at a cow and say, "I think I'll squeeze these dangly bits here and then drink whatever comes out?"
Why do toasters always have a setting which burns toast to a horrible crisp that no-one would actually eat?
The toast one is particularly interesting. Can anyone hazard a guess?
