Well blame it on Anne Moeller of Clio, Michigan for creating this day. On the first Friday the 13th of 1982, Anne's alarm clock did not go off, and she over slept. As a result, she was late for appointments all day long. According to the story, she spent the day spreading the blame, and making excuses for being late.
Since then, Blame Someone Else Day occurs on every first Friday the 13th of any given year. I think we could celebrate this event more often as politicians to blame their opposition left and right who to blame on what.
Blame Someone Else Day could just be your day. But, watch out..... any blame you place today, can come back to bite you tomorrow. After all...what comes around goes around.
Now who would I blame on what happened to my dentures then as well as other unfortunate things happened to me today? XD
