There are many subjects that could be at the very core of a funny joke. In most cases, however, it would require that it was short enough to keep your attention and that the punchline had a big enough twist that it left you laughing. There is a very fine line that needs to be walked and a balance that must be struck if you want to enjoy a joke and get a good laugh. The joke that is below about a woman who will never get caught cheating has all of the features necessary to get you chuckling.
A woman is in bed with her lover, who also happens to be her husband’s best friend.
They make love for hours and, afterward, while they’re just lying there, the phone rings.
Since it’s the woman’s house, she picks up the receiver. The best friend listens, only hearing her side of the conversation:
“Hello? Oh, hi… I’m so glad that you called… Really? That’s wonderful…. Well, I’m happy to hear you’re having such a great time… Oh, that sounds terrific… Thanks. Okay. Bye bye.”
She hangs up the telephone and her lover asks, “Who was that?”
“Oh,” she replies, “That was my husband telling me all about the wonderful time he’s having on his fishing trip with you.”
