Replenishing Puns

A triathlete walks into a bar to replenish some carbs after a hard workout and orders a beer. "I just got done doing a 10-mile open water swim," he brags to the bartender. "Ten miles, huh? That's impressive," the bartender replies. "I'd struggle to do that much on a bike." "Yeah, well bikes aren't that good in water," the athlete says.
