Dwight asks the Benjamin Franklin impersonator who is king of Austria, to which the man replies: 'Joseph II.' Joseph II was archduke of Austria. Austria never had a king, although the arch-duchy of Austria was merged into the Austrian empire with the other countries on Habsburg control in 1804.
The Ben Franklin impersonator says that he "invented electricity." As a naturally occurring phenomenon, electricity cannot be "invented."
Dwight claims the only stripper he's seen is Jennifer Garner on Alias (2001) ("It was one of her many aliases.") However, Sydney (Garner's character) never went undercover as a stripper on the show. Dwight was likely remembering times she portrayed a prostitute, not a stripper.
