A technique whereby odd stories and silliness help people remember dry material. I use it often and it sometimes ticks people off, but if it highlights a point, it may at least by helping some readers/listeners remember. True, it may also offend some such that there can be trade-offs.
Now, all you need is a point.
{Indeed. Nothing wrong with funny, engaging, risqué, even controversial stories. Top's recent "stories" have been none of these. They've been dull, sexist, and vaguely vulgar. I have no memory at all of what they were intended to help me remember, except the fact that I wouldn't risk inviting Top to a casual barbeque, let alone a dinner party. The guy sounds like a bit of a creep.}
I can assure you that I'm a jerk in person too :-)
