Capitals fourth line forward Liam O’Brien is becoming a fan favorite in D.C. I’m not sure if it’s for his general fearlessness or his tongue-wagging. Actually, no. Check that. It’s definitely for his tongue.

On Wednesday, readers at tonight’s STH Party at the National Zoo tweeted us saying they met WWE’s Sheamus. They made sure to tell him they loved his extracurricular tongue taunts. But there was only one fan who could get O’Brien to show off that trademark organ.
