doohickey

Keep an eye out for surprise guests: Last year at the Bowl, Nelson brought out John Densmore of the Doors to play various percussion “doohickeys,” as the singer put it.

For the hard-to-reach places — the flower beds and under the azaleas — he has a little handheld doohickey, like a garden center jack-in-box.

It’s one of those little mechanical doohickeys where you push it in, then it pops out.

Even if it’s a doohickey without any particular monetary value.

You simply slot the little thumb drive-sized doohickey into the appropriate slot in your sleeve and pair it to your phone.
