LOL, I sent a letter similar to that to a buddy. The return address was from Norwegian Penis Enlargers. Stamped in beg red letters of the front of the envelope was "RECALL NOTICE - OPEN IMMEDIATELY!"
Way back in the day, I was teaching him how to use aol instant messenger. We were on the phone as I I got it working for him, I wrote some rather nasty comments to him and he laughed and said he was going to report me to aol.
And the MFer actually did!
He hit the report user button and I got an email from aol the next day that actually had some of the nasty stuff I had written to him in quotes and they warned me that I would be banned if it ever happened again.
So I knew I would get my revenge.
About a year later, I helped him move to NC and while we were there, he told me about all of the hot chicks that worked in the office at the condo association. He brought me there and there were four of them and each one was very hot.
Later I saw a post-it on on the door to his condo. He said that when UPS or Fed-Ex came, they dropped the package off at the Condo office and they put a post it on his door to let him know.
I asked him if I could borrow his radar detector for the ride home and I would mail it back to him.
The label had a fictitious video store from NY and in big letters it said:
CAUTION: VIDEO ENCLOSED
FAT GUYS WHO LIKE NAKED COLLEGE BOYS VOL. VII
Sure enough, he got a post it on his door and when he went down to pick up the package, they all looked at him and started laughing. He was so pissed, he said he wanted to move after that.
