While drinking is undeniably the #1 college pastime, there are still plenty of other things college students do to avoid studying, reading or writing.

Today, we took a look at a longtime favorite of mine: the flash mob.

For the uninitiated, a flash mob is a group of people who gather at a specific location at a predetermined time and perform a random activity at the sound of a whistle.

Some involve simple, basic tasks, such as freezing in place; others are little more… absurd.

Here are twelve of the best strange, absurd, creative ones ever (in no particular order):
