Had a real fun one this week....
Got one of the many pieces of junk mail from the AARP. It was at something like $5 a year for a membership, but I can spend that on annoying my wife, so I did. Got the card(s) in the mail. (Since I signed up it automatically makes her a member too) so I was able to proudly hand it to her and say "HONEY!!! You're AARP card is finally here!"
