Funny Joke: A woman jumps into bed with her lover

 

A woman jumps into bed with her lover and starts getting frisky. Suddenly, the door bursts open and her husband walks in. 

The woman quickly jumps out of bed and starts jumping up and down on the spot.

"What are you doing?" her husband asks.

"I'm just trying to get rid of some energy," she replies.

The husband looks at her suspiciously, but eventually gives up and leaves the room. The woman turns to her lover and says, "I told you my husband was stupid. 

He thinks I'm exercising!"
