My grandson asked why I always tell him to brush his teeth before bed but let him fall asleep on the couch with a mouthful of popcorn.

I said, "Honey, at Grandma's house, the couch is the bed."

Punchline

"And that's what we call strategic dental planning—tomorrow's problem is tomorrow's toothbrush."
