Mormon Surprise 

When a man dressed in his fancy Mormon underpants sneaks into his sweetie pies bed and lies in wait for her to arrive and give her the "Mormon Surprise".

Jacob snuck into his sweetie pie Mary's bedroom wearing only his Mormon underpants, he crawled into bed, clapped off the lights and waited, when Mary returned home and got in bed, Jacob gave Mary the old Mormon Surprise. Mary was very happy and slept soundly.
