My friend and old flatmate Wille has never been scared to eat spicy stuff for money. Many years ago he ate a HUGE chuck of wasabi for some money and now here he is eating a full table spoon of cayenne pepper
He once dared me to drink 1 gallon (3.8 liters) of milk in an hour without puking for $450. I didn't make it, sadly.
