Slice of Bread Challenge 

Eating challenge where you have to eat a slice of white bread in under 45 seconds with no drink to help. Harder than it sounds, because it dries your mouth pretty quick. Not as bad as the cinnamon challenge. I expected it to be a breeze, but it was harder than I thought. Managed to get it in about 24 seconds though.
