a rather tasteless joke
A joke so bad it could make a dying dog beg for mercy. It's like someone took a punchline and threw it in a blender with a dead fish and called it a masterpiece.
My uncle told this joke at my grandma's funeral. She didn't even die from it.
My teacher used it as a substitute for a math test. I failed.
I told it to my pet goldfish. He swam away in disgrace.
