I've got a head like a wiffle ball

Yesterday evening we went for a walk after dinner when I was struck in the head by a rogue wiffle ball. It came out of nowhere, pegged the top of my head, and sailed off again—clearing half a yard and a driveway before landing on the grass on the other side.

Two kids came running out to the street, one was holding a bat. They apologized and made sure I was alright, which I was...because it was a wiffle ball.

Still, I was a little dazed. It hit hard enough to make an audible 'bonking' noise and caused me to bite my tongue (out of surprise or because of the impact? I'm not sure). My head was a sore for a a little while, but I'm fine now. Had it been a baseball it would have been a different story, I'm sure. Mostly it was just...surprising.

When I put the kids to bed last night Rachel said, "Good night, wiffle ball head."

This made me think of the "theme song" for Camp Cariboo, a television show we'd occasionally watch after school when I was younger—I've Got a Head Like a Ping Pong Ball. I suppose it's really just an annoying camp song...but it was also their theme song.
