After getting the overview of how growlers work (reusable jugs that you can have filled via tap from kegged beer), husband and wife briefly discuss whether they want a growler fill. Wife seems perplexed by the whole thing, so the husband continues explaining that the beer is in a “keg” as they peruse the shop. She says, “Well, why don’t you just get a keg?”
He replies, “Well, then I’d need a kegerator.”
“What’s a kegerator?” lady asks.
“It’s a refrigerator for a keg,” he responds.
