Improvised Umbrella

It's raining and you don't have an umbrella? What do you do? Grab the nearest items, fashion something out of them, and you have yourself an improvised umbrella.

Occasionally, a big leaf or a newspaper will be used for this purpose, and don't be surprised to see someone use a (empty) garbage bag as a raincoat, as all three are Truth in Television.
