Teen Takes 93-Year-Old Great-Grandma To Prom

What started as a joke between the teen and his great-grandma turned into the real thing.

Drew Holm, from Crothersville Junior-Senior High School in Indiana, decided to take it a step further and actually invited his great-grandmother to prom.

According to NBC News, Holm had to get a special exemption from his school in order to get his great-grandma in to prom.

The great-grandmother, Katie Keith, last went to prom in 1940.
