The Shower Head (Ep. 716)

Jerry's parents are staying at Leo's in New York for awhile until moving into Del Boca Vista in Florida and he's miserable in the meantime.  To get them to leave, he gets Leo to break up with his girlfriend so he has to move back into his place and force the Seinfelds out.  This works, but then the Costanzas decide to move there and this causes the Seinfelds to decide to stay.

Jerry and Kramer are disappointed with the low flow showerheads being installed in their building and get black market showerheads to replace them.  Elaine keeps failing a drug test for her trip to Africa with Peterman, but then discovers it is because of poppy seed muffins she's been eating.  In the end, the Costanzas decide to stay and the Seinfelds leave when low flow showerheads are installed in Leo's apartment.

Interesting quote: "If you could perhaps conduct the psychopath convention down the hall." - Jerry to his parents and the Costanzas

Grade: B (Kramer using the showerhead meant for Elephants at the end)
