A guy goes to the supermarket and notices an attractive woman waving at him. She says hello. He’s rather taken aback because he can’t place where he knows her from. So he says, "Do you know me?" To which she replies, "I think you’re the father of one of my kids."
Now his mind travels back to the only time he had ever been unfaithful to his wife and he says, "My God, are you the stripper from my bachelor party that I made love to on the pool table with all my buddies watching while your partner whipped my butt with wet celery?"
She looks into his eyes and says calmly, "No, I’m your son’s teacher."
A husband sees his wife is getting ready to prepare for Passover. "This year I really want to help out." he tells her, "Whatever you need me to do, ask... I will do it." His wife tells him, "Don't take this the wrong way, but the best thing you can do to help is to leave the house and let me get my work done without any interruptions." So the husband does exactly what she asks and leaves.
Three hours later his wife hears him come back in. She shouts, "I thought I told that the best way to help me would be to leave." He responds, "You expect me to help the whole day?"
