Its all fun and games until someone gets blown the F up!

So I walk in and my wife hands me a package with the above enclosed. I'm pretty sure I know who sent it but if you have any ideas please let me know. I also need the addy for the BOTL that sent it. The only bad thing is I'm pretty sure there is some other poor saps addy as the sender on the box! Does this sound familiar to anyone that someone else's addy is on the sender line? Who knows someone that would do that? Well whoevers addy it is, you better strap up because you have been chosen. To the real sender the hunt begins! Please help with any info so the sender can be rewarded for the slap in the face awesome package he sent. My wish list now has a hole in it. Thank you very much!
