Hal: What is this called?
Vince: We're racewalking.
Hal: I've never seen anything like it. The the style, the grace.
Vince: Well, it's not all just about looking good. It's the best low-impact aerobic exercise ever invented, despite what you hear from all those Tai-Chi punks.
Hal: Yeah, but how do you do it?
Vince: Well, the International Racewalking Federation specifies you must have one foot on the ground at all times.
Hal: But-
Vince: And your front leg must remain straight until it's completely under you.
Hal: Something like this?
Vince: Hey! I think you've got it! Look at that, guys. I think we got ourselves a natural!
Hal: [giggles] Wow! Look at me! I can walk!
