"total gross out, absolutely hilarious."
For some sick reason, I find getting someone to barf funny. As the kids say today: "Owned!"

My mother in law is the easiest, ever. We all work at a salon. I own a pug (This will make sense). I got some hair conditioner on my black sleeve. My wife says "That looks like one of the pug's eye boogers!" It wasn't, but the damage was done. Mom went rhythmically wretching straight to the can.
