Lol, looking through this thread, alot of people are dying from accidentially hitting Q because it's beside the W key.
Just bind it to something a little more... farther (I use the P key).
Anyways, I believe my stupidest moment was in SG3. I was playing with one of my friends sebostar123. I had all iron except for leather legs, and a stone sword. He had full leather and stone sword. We spotted a guy out by the underwater whale by the border, and went to go kill him. I killed him with 6 hearts to spare, but started organizing through his stuff underwater, not noticing my air bar. I ended up drowning, and being terrible at following my directions as a spectator, Sebo never found my pile of stuff. -.-
