Jason Segel will strip for laughs.

The Five-Year Engagement actor/co-writer stopped by the TODAY show Wednesday and revealed that he was committed to his role int he romantic comedy -- by getting naked on camera.

"Apparently me being naked is funny-- onscreen," said Segel, 32, who went full frontal in 2008 in Forgetting Sarah Marshall. "In my personal life…. If I take my clothes off it's met with hysterical laughter, for some reason."

Segel's personal life these dayslargely spent with girlfriend Michelle Williams, 31. Last month, Us Weekly first broke the news that the longtime friends are now dating. A source told Us that Michelle "hasn't been this happy in a long time."

Alas, Segel's nude scene in Five-Year Engagement (costarring Emily Blunt) ended up being cut from the film.

"They couldn't find a lens wide enough," he joked.

The Five-Year Engagement opens in theaters Friday.
