Mike and Joe

Two salesmen, Joe and Mike, were stranded by a storm and took refuge in a house occupied by an attractive single woman. In the middle of the night, Joe heard Mike sneak out of bed and into the woman's room. Joe said nothing about it until nine months lated when a registered letter arrived at his office. Clutching the letter, he walked into Mike's office. "Do you remember the night we were stranded by the storm and you sneaked out of your room to be with that woman?"

"Yes," Mike replied.

"You told her you were me, didn't you?" Joe demanded.

"Yes, I did," Mike said nervously. "Why do you ask?"

"Because," Joe replied, "she just died and left me a fortune!"
