Frasier: (to niles)"I tell you, he (martin) gets in here and wants to hear his radio station, and he starts pushing buttons like a lab rat on amphetamines!."
- enemy at the gate
Niles: (to frasier) "Please, prepare to be stomped like a late harvest Gevertstremener!"
- whine club
Niles: Yes, and just the mention of a double-bowl stainless steel sink with integral drain boards makes me hum like a sub-zero freezer!
- four for the seesaw
