Bob was walking through the park when he saw a man sitting on a bench, staring at a sandwich. Curious, Bob approached the man and asked him what was wrong.
The man replied, "I've been staring at this sandwich for hours, but I can't bring myself to eat it."
Bob chuckled and said, "Why not?"
The man explained, "Well, you see, I made a bet with my friend that I could go a whole week without eating any carbs. So now I'm just sitting here, staring at this delicious sandwich, torturing myself."
Bob nodded in understanding and said, "Well, I have a solution for you. How about I take that sandwich off your hands and eat it for you? That way, you technically haven't broken your bet."
The man brightened up and handed the sandwich over to Bob. As Bob took a big bite, he looked at the man and said, "See? Problem solved. And don't worry, your secret's safe with me. I won't tell anyone you cheated on your carb bet."
The man laughed and thanked Bob for his help. As Bob walked away, he couldn't help but chuckle to himself. It was the easiest way he'd ever gotten a free sandwich. And to think, all it took was a little bit of carb-related deception.
