DORCHESTER, Mass. (CNN/WHDH) -- A Dorchester, Massachusetts elementary school is gaga over Gaga.
No, this isn't video of the real pop star. It's the principal of Roger Clapp School Justin Vernon. He lost a bet with his students.
Or rather, they won a book challenge, so he had to dress up like the pop star. Vernon challenged his kindergarten through fifth grade student to read 10,000 books. If they did, he promised to do whatever they wanted.
They did it and wanted him to impersonate Gaga. He delivered on his promise Tuesday.
The other part of the bet? He had to milk a cow while dressed like Gaga. Many students said they liked the cow part best.
