The final Josiah tape is a good place to start, I think. The deranged threats, childing, and exceedingly gay mannerisms are great entertainment value, and who doesn't love a prank call where the pranked engages so vigorously with the prankster?
Give them some of the funnier felony telephone harassment texts after that (not Lizard King, he requires more context), along with such hilarious Fun Fat Facts as how he built his fence backwards, salted his own garden, and abandoned his daughter. Then get them to listen to the 7/25/2022 meltdown audio. If they're not hooked on Pat by the time he's screaming to the police at 1:30 in the morning about grinding black children into pepperoni, they probably won't ever be.
