How to Mess with a Scammer

Hey all! I've been contacted by an obvious Facebook crypto scammer. I'm turning to the internet for advice on how to ruin his day.

He's trying to mess around with Safepal (I currently use primarily a cold wallet, combined with some Coinbase for the small amount I trade with), is trying to convince me that he'll send funds to me, and I'm supposed to send 60% of that amount to some other address. I assume that the scam is after somebody sends the payment, the original amount is charged back in some way, but I'm not entirely sure, as I'd like to make a game plan before fully engaging. How would you use this opportunity for maximum entertainment value?

Assume I'm not an idiot and won't actually get scammed.
