Leave Them On A Nail-Biting Cliffhanger

(I bite off part of my nail, and it starts bleeding. I put a bandage on it, but it keeps falling off. I see a coworker near the supply drawer, and call over to him.)

Me: “Hey, [Coworker], can you hand me some tape?”

Coworker: “Uh, sure.”

(He hands me the roll, and watches me take a piece off.)

Coworker: What do you need to tape, anyways?

Me: “My finger. I was biting on it and guess bit too much off.”

Coworker: “You… bit… WHAT?!”

Me: *suddenly realizing* “MY NAIL! I bit the nail off!”

Coworker: “I shouldn’t have asked.”
