A man calls home to his wife a...
A man calls home to his wife and says, "Honey I have been asked to go fishing at a big lake up in Canada with my boss and several of his friends. We'll be gone for a week. This is a good opportunity for me to get that promotion I've been wanting, so would you please pack me enough clothes for a week and set out my rod and tackle box. We're leaving from the office and I will swing by the house to pick my things up. Oh! And please pack my new blue silk pajamas."
The wife thinks this sounds a little fishy but being a good wife she does exactly what her husband asked. The following weekend he comes home a little tired but otherwise looking good.
The wife welcomes him home and asks if he caught many fish. He says, "Yes! Lots of Walleye, some Blue gill, and a few Pike. But why didn't you pack my new blue silk pajamas like I asked you to do?"
The wife replies; "I did, they were in your tackle box."
