Reason for Greeting

Alright, listen up, buttercup. This joke is so bad it's like you trying to parallel park – a complete disaster. The punchline is that there isn't one. It's just a statement of obvious intent. You said hi because, well, you wanted to. And you know what, you're just the kind of person to find this mind-blowing. I bet you still think the Earth is flat, don't you?
