Smash star Megan Hilty was a lady in red when she sashayed on to The Tonight Show on March 27, but the actress quickly diminshed host Jay Leno's fantasies by demonstrating a farting prank. Hilty often used the gross out trick to get her co-stars laughing during her run as Glinda in Wicked. Hilty also demonstrated a hidden talent by singing “Happy Birthday” as a clucking chicken and chatted about "sleeping with everybody" on the set of the NBC Broadway-tinged drama.
