Dick: Next, we measure the decay with difference delta gamma for the mass eigenstates, assuming CP invariance. The CP eigenstates and the mass eigenstates are... what? Leon?
Leon: Dr. Solomon, are you allowed to dispense ibuprofen?
Dick: Wrong. Pitman?
Pitman: Aspirin?
Dick: Bug? Here!
Bug: Chimps!
Dick: CP eigenstates implies that they are the same.
Caryn: Dr. Solomon, there is no possible way we could have known that.
Dick: Oh, really? And yet, my son knew that. Didn't you, Tommy?
Tommy: Well, I thought I knew that until you started explaining it. I can see them not getting it.
Dick: Oh, yeah. I know. As usual, I'm handing out sandwiches in the cemetery. Class is dismissed.
