Mark: Whoa you guys have good radio. That's Joe Turner's original Shake Rattle & Roll, not Bill Haley's anemic cover.
Cashier: Do you have a store card on file with us?
Mark: Check it out: that's Ahmet Ertigun and Jerry Wexler shouting "shake, rattle & roll!" on the choruses.

Cashier: Do you need help out to your car?
Apparently so.
