Mummy with Uncle Paul

A young daughter is at home when her father calls. The daughter picks up.

"Hello?"

"Hi honey. This is Daddy. Is Mummy near the phone?"

"No Daddy. She's upstairs in the bedroom with Uncle Paul."

A brief pause. "But honey, you haven't got an Uncle Paul."

"Mummy says I do! He's with Mummy in the room, right now."

Another brief pause. "Uh, alright, here's what Daddy wants you to do. Put the phone down on the table, run upstairs and knock on the bedroom door, and shout to Mummy that Daddy's car just pulled into the driveway."

"Okay Daddy, just a minute."

A few minutes later, the little girl comes back to the phone. "Okay, I've done it, Daddy."

"And what happened, honey?"

"Mummy got all scared and jumped out of beds with no clothes on and ran around screaming. Then she tripped over the rug, hit her head on the dresser and now she's not moving at all!"

"Oh my god!!! What about the Uncle Paul?!"

"Uncle Paul jumped out of bed with no clothes on too! He got all scared and jumped out the window into the swimming pool. But I think he doesn't know you took out the water last week to clean it. He hit the bottom of the pool and now he isn't moving too!"

A long pause this time. "Swimming pool...? Is this 486-5731?"
