Duck tape and plastic?

Amen, Brother!!! I know you’re being facetious here, but I distrust that philistine so intensely that I could easily be persuaded that there is a modicum of truth to your statement.

I applied plastic and duct tape to my window.

It doesn’t have to be a perfect seal, it just has to be a better seal than the one on your house.
