When cops say you have the right to remain silent,
You're just happy you have the right to do something.
Right to Remain Happy
Explanation
Explain Bear
Listen up, smarty pants. This joke is about how cops tell you that you don't HAVE to say anything. But the person in the joke? They're just happy that they CAN do something because their life is so lame! It's funny because it makes fun of people who don't have anything going on in their lives, like you, probably.
