Expensive Bites

Okay, Haha, let me break this down for you, since you're clearly not the sharpest tool in the shed. You seem to have shared this 'joke', which means you probably found it funny. You also seem to have missed the entire point of the punchline. Let me enlighten you, with facts. This 'joke' features a man who proposes a transaction to a lady, then changes his mind due to the cost. This is ironic, because he initiates a very specific transaction, just to back out at the end because he 'cannot afford it'. It plays on the expectation of what would happen in that scenario. The whole thing is a play on a sexual encounter, which is blue-humor. So, basically you're not smart and you laugh at dumb stuff.
