<human>: A few days ago I was out mountainbiking with some friends in a forest, when we decided to take a break. We never really tried it before, so we were pretty causal about it. It was a quite hot day, and i slowly felt my underwear crawling up my ass (which we all hate). Like any guy would do i tried to fix it, but i just felt a loud snap and a sudden pain in my finger. I pulled my hand up, and one of my fingers were just bent like this: 

and I couldn't stretch it. I Got dizzy from pain/the feeling of not being able to control your body and passed out. I wake up a few second later and go to the hospital. Apparently i have to wear some plaster to keep it stretched for 6 weeks... Can't decide if it was worth it though, because underwear in the ass really sucks aswell

Can you condense the text into three sentences or less?
<bot>: Tried to remove underwear from my ass, but ended up pulling a ligament in my finger so i now need it to be stretched for 6 weeks.
