Where's Your Mother? 
Family Jokes
Submitted by outward

I walked into my sister's kitchen and found my nephew having a snack. "Where's your mother?" I asked.

"She is upstairs, said she was going to take a shower. Hang on, let me check."

He stepped into the nearby bathroom and flushed the toilet. A second later a sharp yell came from upstairs.

My nephew walked back out and said, "Yep, she's in the shower."
