The term is often used misleadingly to refer to the sting played by the drummer in cabaret shows to accentuate the punchline of a joke. As a result, a particularly obvious laugh line is sometimes called a rimshot.
Hopefully some of these stories will give you a chuckle without the added emphasis of a rimshot.
To bring a smile to others with original humor does my heart good.
Look around. I'm sure there is something here that will make you chuckle and just possibly make you bust out in a belly laugh.
Good hunting to you.
