Tim: When hanging a light fixture or heavy mirror, what's the first thing we need to do, Al?
Al: Find a stud, Tim.
Tim: And I think we've come to the right place, haven't we? [chuckles] Al, do you recognize this?
Al: Your razor, Tim?
Tim: No, actually, it's your razor, Al. I picked it up backstage. An electric razor can double as a stud finder. [turns it on and holds it near Al] No stud there. Actually, Al's electric razor can be a stud finder. If you listen, the sound of it changes the closer it gets to a stud.
Al: My mother gave me that razor, Tim.
Tim: Why? Did she go back to blades? This razor can not only keep Al's mother whisker-free, it's a handy way to find studs around the house.
