This is actually four different quotes (warnings, really) all related to the Swanson Family Mash Liquor Ron’s mom, Tammy One, Leslie, and April were drinking.
“That’s Swanson Family Mash Liquor, made from the finest corn ever grown on American soil. It’s only legal use is to strip varnish off of speed boats.”
When Leslie wanted to try it:
“Leslie, No, don’t drink that. We use it to burn warts off of the mules.”
When April wanted to try it:
“April, No, That stuff will melt the shell off a garden snail.”
Before Ron pounded the whole jug:
“Okay, this ends now!”
