Oops
A newly married couple went to a family picnic at his parent's house.
The new wife was doing her best to learn the names of brothers, sisters, cousins, and all of the associated wives, husbands and children.
However, there was one guy there that she just couldn't keep his name straight in her mind, no matter what she tried.
Finally, he bailed her out, telling her his name was Dick.
"Of course!" she said quickly, without thinking.
"How could I ever forget? You even look like a Dick."
