A woman gave a beggar 50 cents. The woman is the beggar's sister, but the beggar isn't the woman's brother. Why not? (this actually stumped people!)

The beggar is the woman's sister.]
You walk into the kitchen and find a ping pong in a glass bottle. The neck is big enough for the ping pong to fit through, but it's too small for your hand to fit through. Without breaking the bottle or tilting it so the ball will roll out, how would you get the ping pong out? (made this one up on the spot so I don't know if there are more than one answer or if it's told properly).
[
Use a hoover to suck the ping pong ball out!
Or... just fill up the bottle with water.]
