Is it normal that i would do anything as long as its a challenge.

It goes like this, Like the next person i hate doing chores, boring stuff, favours, you know stuff like that. But if you challenge me to do it in a unusual manner then i would be bound to accept it (provided its creative n funny).
For example last year ma friend asked me to pick some furniture up from a city 40 miles away. I refused. But then he said "if u pick da stuff up, wearing nothing at all, then you can in turn sleep with my girlfriend" his girlfriend wasn't really my type, BUt the challenge! So i did it. Anyone who watches HOW I MET UR MOTHER with barney(challenge accepted!) knows what its like. Problem is however you wont shy away from really degrading stuff as long as its a challenge.
So my question is this, is this normal?
