By: Brandon Voss

Neil Patrick Harris has a new Instagram account, you guys!

For his third post, The How I Met Your Mother star shared this awesome photo of himself and fiancé David Burtka dressed up as tweedy fictional detective Sherlock Holmes and his sidekick Watson. So what's the tea?

"At our great friends, Becky Baeling & Kris Lythgoe's murder mystery wedding," NPH wrote. "The game, as they say, is afoot."

Top that, Lucy Liu.
