What are the many uses of an army poncho liner (a.k.a. a wubbie)?

My sweetheart came to see me on his mid-tour leave and gave me a wubbie . He told me there were many uses for it though, I was just wondering what some of them were.

Anything a blanket is capable of it is and more. Like those blanket sock things you see on the infomercials. You could put it on and it would be like a blanket over you that you could move around in. Would work for sporting events, anything outdoors really, you could take it with you to the fourth of july fireworks.
