i actually overheard the Mulva line used the other day.
i was in a bagel shop, evesdropping, when a woman walked up to some guy she hadn't seen in a long time.
She's all "Hi, how are you!! I haven't seen you in a long time, where have you been?"
He says "Hi, how are you, great to see you...." then turns his head slightly to his friend "Mulva"
She leaves and i turn to him and said "Her name is Delores"
He looks at me puzzled and i see the gears moving in his head. then it dawns on him what i said.
Everybody cracked up!!
