In bed with..

An elderly woman comes home and finds her daughter in bed with a vibrator. She screams at her, "What are you doing?" The daughter says, "Mom, I'm 40 years old, I'm not married and I don't have a date. Give me a break!" The mother shakes her head and leaves. The next day, the father walks in on the daughter and finds the same thing. He screams, "What's going on here?" The daughter says the same thing to him, he shakes his head and leaves. That night, the mother comes into the kitchen and finds the father sitting at the table, a beer in one hand and the vibrator in the other. She says, "What on earth are you doing with that?" The father sits back and replies, "Hey, leave me alone, can't a guy have a beer with his son-in-law?"
