New Girl Recruits Alan Ritchson as Jess' [Spoiler]-Challenged Beau

New Girl Alan Ritchson

Someone needs to tell Aquaman it’s not the size of the wave that matters, it’s the motion in the ocean — but will that person be Jess?

We’ll find out this fall when Smallville alum-turned-Blue Mountain State jock Alan Ritchson guest stars on New Girl as a good looking guy that Jess meets at the bar. The twist? Dude proves to have some, ahem, shortcomings below the belt.  (Psst. He’s got a tiny penis.)
