For the fourth year in a row, a group of insane people will board themselves up in a small, Mushroom Kingdom-decorated room to beat every level, collect every star and stomp every Goomba the Super Mario franchise has ever produced. Why would someone purposefully, harmfully oversaturate themselves with such a wonderful, timeless franchise? Because they're the Mario Marathon. It's in their blood.

The crew is kicking off this suicide mission today at 11 a.m. ET, starting with a playthrough of Super Mario Galaxy 2. Even though it hasn't started yet, the event has already raised $13,000 for Child's Play. We encourage you to go watch these poor souls hurt themselves with Mario, and then, if you feel so inclined, reward their efforts with a donation to a good cause.
