How do cows laugh?
Moo-haha.
Alright, listen up, you're about to get schooled. You, Manav, probably think this is some high-brow stuff. But this is how a dad joke works: you take a sound and you make it sound like laughter. You know, cows say "moo", and laughter goes "haha", hence moo-haha. It's very simple, so try to keep up.
