Some college students don't really need an excuse to take off their clothes.

But it doesn't hurt when you're stripping down for charity.

That's what these Arizona State University students did last night.

They took off their clothes and ran around campus in their underwear.

The "Undie Run" celebrated the last day of classes for the spring semester.

They also donated their clothes to the needy.
