Happy Birthday Dr. Seuss!

If you've checked out Google today, you've probably noticed that the lettering has taken the form of some of our favorite Dr. Seuss characters.

Dr. Seuss, otherwise known as Theodor Seuss Geisel, is celebrating his 105th birthday today.

According to the Star Ledger, Geisel took the pen name, "Dr. Seuss," as a freshmen at Dartmouth College. Geisel was the editor-in-chief of the school paper, the Dartmouth Jack-O-Lantern. He was forced to resign from activities after getting in trouble for throwing a drinking party during prohibition. In order to keep his job on the school paper, Geisel came up with the pen name, Dr. Seuss.

Many school children are celebrating today with Read Across America Day, according to Newschannelfive.com.

So take the advice of Dr. Seuss today: "If you never did, you should. These things are fun and fun is good."
