VIDEO: Capitals' Oshie surprises 5-year-old who was upset about his trade

There's nothing sweeter than a child's smile.

A video of 5-year-old Libby Lu crying about the trade of her favorite player, T.J. Oshie, from the St. Louis Blues to the Washington Capitals went viral earlier this week - and the NHLer surprised the youngster Thursday.

Libby and her father Jimmy joined ESPN's "SportsCenter" to talk about the video that made her so famous, but little did they know her idol was in on the entire thing.

Libby was a little starstruck by the chance to talk to Oshie, but managed to ask the 28-year-old the one question on everyone's mind: "Do you have a swimming pool?"
