Meet Apostol Stoyanov, a real life Billy Madison. The 78-year-old Bulgarian man has just started off the new school year like hundreds of children young enough to be his great-grandchildren ... in first grade:

Apostol Stoyanov from the central village of Popovtsi never got a chance to attend school when he was a kid and decided to enroll in first grade this year, at the age of 78, the state BTA news agency reported citing school officials.

The elderly man, who attended the start of classes Thursday in Gabrovo alongside another 430 first graders, told the agency that he was illiterate but had already started practicing to write letters.

Maths scared him but he expected teachers to help him.
