Amphetamine addiction! Drugs in my record!

when I tried to put the record back in the sleeve it wouldn't go in all the way? I couldn't figure it out I tried every angle, still wouldn't go in. So I stuck my hand inside the sleeve to see what was up and I found a folded up piece of foil stuck in the back corner inside the sleeve.

Euclidean police report !

If the wrap is in the corner it would not have hampered the record going back in the sleeve as a circle does not trouble the corners of a square it's own diameter.

Unless the record was square ! Or the wrap was massive.
