I guess 25ish years?

There’s a comedian I saw on An Evening at the Improv in the late 1980s who was doing a detective schtick.

The joke I remember is “Either this man was stabbed to death with a spoon, or his entire body is breaking out in little smiles.”

I searched and searched for the clip and finally found one link, just one…

That was me having asked the same question a decade prior.
