What's the best prank you ever pulled - successfully?

This happened a while ago- back when people sent out Christmas cards and you always got samples of cards to buy.  One year I took one of the sample cards, crossed out the message and wrote:  "Things were a little tough this year so we're working on cutting back on Christmas expenses.  But it's the thought that counts, so Merry Christmas."  Mailed it to my brother in-law at his office address with no postage and his home address as return address.  Worked perfect too, had to pay his own postage for our Christmas card that year.😈

To me it's funny but maybe you had to be there....

Found a pregnancy test strip thing in a parking lot.  And put it in my 15 year old daughter's bathroom trash can for my wife to find.  

Her face went completely white, and she was afraid to talk to me for the rest of the evening.   

I let her off the hook right before the explosive text messages to my daughter began.   Daughter is 28 now and we still don't have any grandkids out of her 👍

I might have to try that next year when the wife mails them out. Stamps just keep on rising and the service just keeps getting worse.
