When Mark Wahlberg accepted this challenge, everyone knew there would be no competition. After all, if Wahlberg could play a Boston cop in The Departed, he can definitely fire a few watermelons at a target. And so, the crowd looked on at Wahlberg and Fallon (particularly at Wahlberg’s well-toned arms), and perhaps wondered, “Why are there so many melons? Why are we standing here? Why aren’t Jimmy and Mark enjoying an intimate picnic right now?†So many questions, so many melons, such little time.
