What is an old mid-western expression i could use on these milenials at work to make them think i just made up to "blow thier mind?

@LvChris ahh, mule muffins!

@LvChris when i was 20, i knew a hard boiled mechanic Texas, that used to look at me and say " aww rabbit piss, damn kids, hanging around the airport" ..i was always walking away thinking "huh" confusion was what he wanted lol

@LvChris the best was from that psychiatrist Sydney Freeman when he said when he first appeared and when he last appeared " ladies and gentlemen take my advice pull down your pants, and slide on the ice, I forgot that one that was one of my favorites and I'm going to start using that at work

@LvChris it was so good to see him use that same line at the beginning of the show after all those years and then use it at the end of the show
