Here's something we hear a lot this time of year when people feel too lazy to say the full St. Patrick's Day name - they shorten it to St. Patty's Day or St. Paddy's Day.

According to the site PaddyNotPatty if you say St. Patty's Day you are wrong. Though it makes sense to use the letter 'T' since the name is Patrick, if you call a guy named Patrick, Patty then you'll probably get a punch in the face.

Add to that the fact that this is an Irish holiday (not saying all Irish are violent) you'll probably get more than a punch in the kisser.

Paddy Not Patty has loads of other useless information on our favorite drinking holiday.
