The ultimate physical, mental and manly challenge. Training and experience is a must. To successfully sleep with 5 different girls in one night.
Rules are simple. No paying and all different places. All at once is impressive but doesn't count.
Can obtain style points by riding "The Tri-cycle" (threesome) across the finish line.
Man #1: I just completed the iron man challenge and obtained this championship belt.
Man #2: Dude, i did it do. But obtained mad style points.

The challenge of masturbating to any 5 Lady Gaga music videos within a 24 hour period.

Restrictions are: You can only watch 1 music video at a time. The videos must be on your history. The participant CANNOT be drunk.
Oh my God, I was so bored over the weekend I tried to finish the Lady Gaga Iron Man Challenge.
