From a teen’s account of visiting Yellowstone:

Our next stop was what we had come here to see: the infamous Old Faithful geyser. Scheduled to erupt every 92 minutes, we waited impatiently.

I know if I were scheduled to erupt every 92 minutes, I’d be impatient too!

(For those who’ve forgotten their grammar lessons, the second sentence is called a dangling participle … it’s one of my favorite boo-boos because it generates fun constructions like this one.)
