The spark had been lost in this guy's marriage, so he was trying to think of a way to re-kindle it.

One night he came home from work and found his wife asleep in bed.

He thought to himself, "What can I do to show I still love her?"

He proceeded to get under the covers and go down on his wife. Soon she began to gently squirm and moan in pleasure.

After a few minutes, her body spasmed with ecstasy as she climaxed.

Afterwards, the man went straight to the bathroom to brush his teeth.

When he got there, the light was on and he saw his wife there shaving her legs.

He exclaimed, "What are you doing in here?"

She said, "Shhhh!" pointing at the bed, "You'll wake your mother."

that's just plain

I think a better and less gross punch-line would be 'shhh! you'll wake my mother.'

Ewww!

I think a better and less gross punch-line would be 'shhh! you'll wake my mother.'

Sorry for the 'gross' punchline. Both images (mum or mum-in-law) are equally horrific, but in hindsight, I agree with you!
