A husband and wife were invited to a halloween party. The husband had his costume on and was ready to go, but the wife was feeling sick and told the husband to go on with out him. A little while later the wife was feeling better and got dressed up in her costume and went to the party.
When she got to the party she knew her husband didn't know what costume she had on, so she decided to have some fun. She found her husband and went up to him and started dancing with him. The husband danced back and the wife leaned in and whispered in his ear to go and have sex. He agreeded and the two went and had sex in a bedroom. After the sex the wife raced home.
An hour later the husband returned home, without his costume on. "Where's your costume?" asked the wife.
"Well, when I got to the party and I took it off and went and played poker, but I gave it to your dad."
