Back in January, Instagram user Hannah Delmonte asked Philadelphia Eagles linebacker Emmanuel Acho if she could take him to her prom. She figured 2,000 retweets would be a fair asking price, but the Eagle countered: 10,000 retweets, he said, would be the price to make her "the happiest girl alive."

Well, Delmonte got her 10,000 retweets (and more), so when Acho returned from a trip to Hong Kong, he went tux shopping and surprised his fan at her school with a signed Eagles jersey with the number 15 and "PROM" written on the back.

Asking athletes and celebrities to prom has become a much more popular thing over the last few years as interacting with them has become much easier through Facebook, Twitter and Instagram, but it's still cool that Acho took the time to make his fan's dream come true. Scroll through the slideshow above to see the step-by-step process of how this all went down. (If the slideshow doesn't work, click here.)
