April Fools' Day is a pseudo-holiday celebrated on April 1st of each year. On April 1st, watch out for people trying to trick you or get you to fall for a practical joke. Some of the best April Fools' hoaxes end up on the news!
One of the only April Fools's pranks I can remember falling for happened while I was attending Ohio State University. When I was there in graduate school, one of our professors devised a plan to tell all of us poor students that our computer lab would be closing and we would all need to purchase new laptops. Since the professor who came up with this plan was a little bit of a jokester, we would have all suspected it was a trick if he delivered the news. Instead, he had one of the most droll dry - Ben Stein sounding - instructors deliver the news instead. Coming from him we all bought it. We were outraged and panicked at the idea of this new expense on top of our grad school tuition. The next day, he filled us all in on the truth. Hardee-har-har. He definitely got us. We were all so consumed with studies and worries that none of us even realized this fake announcement was made on April Fool's until the next day. ;)
