1. A Box of Poop
2. A Cardboard Penis
Ah a classic, personal favorite of mine. ShipADick can make all of Andy Samberg's Loney Island dreams come true; it will literally send dicks in a box.
3. A Bag Full of Dicks
4. A Fuck Ton of Glitter
5. A Butt-hurt Care Package
6. An Anal Probe
7. An Envelope of Mayo
8. The Middle Finger
Why not go with a classic? So simple, yet super effective. Bird by Mail will anonymously send your enemy literally just a piece of paper that reads "Hi!" to offer a false sense of security, then when opened reveals a big, fat middle finger.
Send 4 rubbers to someone who should really wrap it before they tap it, for humanity's sake.
10. Prank Candles
WTF Candles are revenge served extra cold, as they offer the appearance of a nice present, but in actuality are a ticking-time bomb of a baby's diaper, of sweaty ass, or of man fart. Excellent.
11. A Piece of Gum
Is your enemy's ass jealous of all of the shit that comes out of his mouth? Let him know! While not so much as a malicious gift, but rather, a valuable piece of advice, BestPranksByMail will ship that one person who "forgets" to brush his/her teeth each morning an anonymous note explaining that they smell like pure shit.
12. A Brick
14. A Shit Load of Fake Money
Nothing like destroying someone's false sense of hope and excitement! Send this douchebag a stack of $50,000 in movie prop money here.
