The Glasgow Ice Cream Wars were conflicts in the East End of Glasgow in Scotland in the 1980s between rival ice cream van operators, over lucrative territory and suggested use of ice cream vans as a cover for selling drugs.

The conflicts, in which vendors raided one another’s vans and fired shotguns into one another’s windscreens, were more violent than might typically be expected between ice-cream salesmen.

Ice cream is no joke.
