We find out in The Cooper-Nowitzki Theorem that Sheldon knows
Morse code ("I'm invoking the Skynet clause of our friendship
agreement."). That means the three short taps in the triple-Penny-knock
could be the S of "SOS." Or possibly he's hissing like a deflated
bicycle tire. Or maybe it's an "s" like in "Pssssssst!" That works. That
way the knock both performs the function of getting the intended
recipient's attention and also communicating information about the
nature of the conversation. Okay. Maybe not. One thing we do know for
sure is you don't want to ignore him. Cause he ain't going away.
"knock knock knock Penny! knock knock knock Penny! knock knock knock
Penny!" in white on a black 100% cotton t-shirt.
