When someone mentions the name Jason Segel, what pops into your head? Possibly one of his memorable characters in the many Judd Apatow films he's been a part of? Maybe his brief part in Can't Hardly Wait? Or, how about his role as Marshall Eriksen in How I Met Your Mother? Yeah, there's plenty to choose from, but as InStyle found out, his girlfriend Michelle Williams "didn’t actually realize who he was before I started dating him."

While Williams does say she saw The Muppets and thought it was cute, the 32-year-old actress "didn’t realize he made a lot of very popular, funny movies or was on a TV show.” Um, what? Afterwards, Michelle mentioned how, at 5-foot-4, "maybe more important, I didn’t realize he was so tall [6’4”]. I thought, ‘Hey, man, you’re cramping my style!’ I tried wearing wedge heels for a while to compensate, but it wasn’t me and I just gave up.” Wait, wait! Yeah, height difference is crazy but don't change the subject. You really didn't know who Segel was before you started dating him? Wow. Just wow.
