>I've tried to employ the "drunk looking for his keys under the streetlight" metaphor before but was met with confusion and blank faces.

It also deals with another matter as a metaphor. It's about doing what's easier but without effect, over what's effective but difficult.

Bikeshedding is about wasting time on non-important decisions.

So there's only slight overlap between the two concepts. The "talk about furniture arrangements while there is a hole on the roof" parent mentions is more apt -- but you can also bikeshed without any more pressing matter present.

The version I've heard is: "rearranging the deck chairs on the Titanic" :)
