You know, that makes sense, I anthropomorphized the fridge and had it literally shrinking clothing, maybe to keep the food, the glutton that the fridge is.
I understood and liked the joke. It would flop in a standup set but get some chuckles if you dropped it in context at a social gathering. There is nothing wrong with the wording either despite what others are saying
Using the wrong setting on a clothes dryer can cause certain fabrics to shrink. People that are gaining weight would often blame the dryer for shrinking their clothes rather than take some personal responsibility. Hence the joke is they thought it was the dryer shrinking their clothes but it was them overeating aka the refrigerator's fault.
