Target selection

Play this on a kid who is a chronic liar or phony. Ideally your target is someone who normally sits near you on the bus, in class, or in the lunch room.

Setup

1. Select a few friends to be in on the gag. The more people involved, the more effective it is. 
2. Tell them to laugh hysterically when you deliver the punch line to your unfunny joke.

Execution

1. Wait until your accomplices are in place and the target is listening to the conversation.
2. Tell the unfunny joke, and deliver it like it's pure gold. (See example joke below.)
3. Along with your accomplices, laugh your butt off like it's the funniest joke ever told.
4. Here's the key: Watch the target to see whether he pretends he gets the joke. If you chose your target wisely, he'll start to laugh too.
5. At this point, look at the target and say, "Dude, that joke was totally not funny!"
6. Bask in the glory.

Example joke

This joke is totally not funny:

Two Eskimos are sitting together at a fishing hole. One Eskimo says to the other, "Hey will you pass me some bait?"
