Dilbert arrives at home carrying his briefcase. Dogbert sits on the couch armrest. Dilbert says, "My boss is making the engineers compete in an 'Iron Man' event. It's supposed to improve teamwork." Dilbert sits on the couch and says, "I'm glad I take the stairs sometimes instead of using the elevator. I'm in pretty good shape." Dilbert flexes his arm and feels his bicep. Dogbert says, "Yes, you are, to the extent potato is a pretty good shape." Dilbert says, "I just wrenched a muscle."
