A fellow picked up a girl in a bar and took her home with him. After some preliminary drinks and talk, they got undressed, climbed into bed and generally got organized for a leg over.
After a few minutes, the girl started laughing.
The fellow asked her what she found so amusing.
"Your bat," she replied. "It's a bit on the small side."
Feelings hurt, he replied: "It's not used to playing in Yankee Stadium."
