mice talking about cheeses

One day three women went camping - a blonde, a brunette and a redhead. The blonde suddenly had to go to the bathroom. She went into the woods with her toilet paper and did her business.
While she was gone, the brunette and the redhead decided to play a joke on her. They skinned a rabbit and snuck up on the blonde, put the guts behind her and ran back to the campsite. Three minutes later they heard a scream.

Then they waited another half an hour and the blonde came back, sweating. She said, "I had to poop so hard I pooped my guts out. But with the grace of God and these two fingers, I think I got them back in."
