Joke: Flirting and falling flat

Teeing off on the 12th hole at a golf resort, we stopped to buy cold drinks
from the young woman driving the beverage cart.

As my buddy reached for his wallet, he flirted with her a bit, saying to
her, "You're in great shape. You must work out a lot."

Flattered, she gave him a big smile and gushed, "Oh, thank you so much!"

The next day a different young woman was driving the cart.

"Watch this," I whispered to a different buddy. I walked up to her and said,
"Wow, you must work out a lot."

"Yeah," she replied, dryly. "You should try it yourself."
