The One with Interspecies Friends (S02E04)

On game night, it turns out Jackie knows a ton about Debbie -- but not vice versa. Dick learns that Marty eats too much and unhealthily. Debbie sets off to learn more about Jackie, and Dick wants to get Marty in shape. One task sounds harder than the other, but it's probably not the one you'd think. You see, Debbie keeps turning opportunities to learn about Jackie into something about her. And Dick gets hurt on the treadmill and Marty finds a way to find every vending machine at the hospital. So nobody's plan is going very well. (ABC TV Network)
