The Duckening
Wow, one or five wasn't enough huh? You do realize that when they open this package ducks are gonna go flying eveywhere right? Alright, then. Unhinged behavior, but I'm into it.
Your chosen recipient will receive a handfull of 20 randomly colored, tiny, plastic ducks with a card telling them they've just been ducked.
If you've got the makings of a super-hero villian you can select the "personalized message" option and explain to them exactly why they've just been ducked, otherwise it will be completely anonymous. Think of the drama.
Disclaimer: Keep in mind you can't go crazy with the personalized messages here. Keep it short, fun, and only moderatly looney. If you give off stalker vibes or get too gross I'll just cancel your order and refund your money.
