Even with his departure
from Saturday Night Live
and his transition to Late Night
, Seth Meyers has found time in his busy schedule to visit a deserving fan.
On the season premiere episode of Say Yes to the Dress
, airing Feb. 21 (9 p.m. ET) on TLC, Meyers, 40, surprises Shealynn Casserly, a medic who was injured in a roadside bomb explosion in Afghanistan.
Shealynn is planning her wedding and looking for that perfect dress while she heals from her injuries, and Meyers shows up at Kleinfeld Bridal in New York City, to help out and prove what he's learned
about dress shopping.
"Fit and flare, mermaid, A-Line, princess, um, evil witch, don't like that one," he quips.
Calling the opportunity to meet the NBC star "a dream come true," Shealynn says, "At points I thought I was making him laugh more than he was making me laugh. It was a lot more interesting than meeting President Obama."
