Welcome to Sweden Exclusive Video: Bruce Commits the Ultimate Swedish Taboo!

As if not being tall wasn't bad enough, on Thursday's Welcome to Sweden, Bruce (Greg Poehler) commits an even bigger Swedish faux pas.

While enjoying coffee with his girlfriend Emma (Josephine Bornebusch) and her parents (Lena Olin, Claes Månsson), Bruce refuses any cinnamon buns on the grounds that he's just not that into cinnamon. Totally understandable, right?

Wrong.

"Hating Hitler is OK," Viveka interrupts. "But cinnamon buns."
