Even the people being pranked would agree that this one was worth looking foolish for.

If two male strangers approach you on the street and ask you to take part in a limbo contest, you should probably keep walking. If the strangers request you wear a blindfold while limboing—or doing anything else, for that matter—you should definitely keep walking. If the same two guys are dressed anything remotely like the guys in this video, and you even think about stopping to hear their pitch, then God bless you. Because you're the kind of trusting person that make hilarious, harmless pranks like this one possible. Limbo!
