(hands thumping) 

- Feeling pretty tight, huh, Mr. Finchley? 

- Yep, Henry. 

- Dad! Dad! 

- Jimmy! 

- I only had one. 

- One what? 

- One cavity! 

- Aw, that's great. You know, Mr. Finchley, since he started brushing with Crest toothpaste, it really made a difference. 

- Why is that? 

- Crest got fluoride, and the others we used didn't. 

- That Crest, that sure takes the punch outta cavities! (Mr. Finchley groans) 

Announcer: Crest with Fluoristan, the cavity fighter.
