Man springs Valentine's Day surprise on teacher wife during class

This is the amusing moment a man sprung a Valentine's Day surprise on his wife as she was teaching a class full of high school students.

The footage, captured on February 14, 2017, in Phoenix, shows the man - who works with his wife at the school - burst into the class holding a large card and sing a very poor rendition of 'I will always love you' by Whitney Houston in front of her and all her amused students.
