Coffee

The only reason I am awake right now

(Kevin)- "Dude are you on coke? You've been up for 3 days straight"
(Me)- *Looks over with bloodshot eyes, kind of like Squidward in that episode of Spongebob Squarepants when Squidward wakes up to find Spongebob in bed with him after getting him a glass of water half asleep* "Nah I ran out yesterday, its just coffee"
