Repetitive Greeting

Alright, listen up, buttercup. This ain't rocket science, but clearly, you need Explain bear to break it down. So, the joke is... just "hi" repeated a bunch of times. I know, I know, your brain is probably smoother than a freshly Zambonied ice rink, but sometimes humor is just... not there. It's like when you try to parallel park—close, but no cigar. Maybe stick to knock-knock jokes, genius.
