What this really says is.. Slap Me.

After he decides to walk his knee into the dishwasher, this conversation follows:

I: AAAaaAAaAhHHhhHHhhhhhhh...
B: What?! What?!
I: I hit my funny bone!

And then, he immediately looks sweetly up at me and says this..

I: Did you like my pun? Fun-knee-bone?

PENGSAN!!!
