Whos dumber

An Englishman, a German, an Irishman and a Scotsman were sitting in a
bar drinking, and discussing how stupid their wives were.
The Englishman says, "I tell you, my wife is so stupid. Last week she
went to the supermarket and bought $300 worth of meat because it was on
sale, and we don't even have a fridge to keep it in."
The German says, "That's nothing! My wife just spent $1,000 on ski
equipment, and she can't even ski!"
The Scotsman agrees that she sounds pretty thick, but says his wife is
thicker. "Just last week, she went out and spent $17,000 on a new car,"
he laments, "and she doesn't even know how to drive!"
The Irishman nods sagely, and agrees that these three women sound like
they all walked through the stupid forest and got hit by every branch.
However, he still thinks his wife is dumber.
"Ah, it kills me every time I think of it," he chuckles. "My wife left
to go on a trip to Greece. I watched her packing her bag, and she must
have put about 100 condoms in there, and she doesn't even have a penis!"
