Hey there, Thumbper. What's the matter?
Ooooooh. Ouch. Plastic bakeware-safe knife, you say? Because I didn't grease the brownie pan properly in haste to watch the hockey game? Because I was rushing to grab a brownie on my way back to the tv and slipped with the plastic bakeware-safe, good-for-lettuce, knife? And what's with the overly-dramatic lighting?
No, I don't think you need stitches. Yes, it's deep but that's what Superglue's for...
Walk it off, Thumbper. Walk it off.
