One of the few episodes where Paddy's pub isn't shown.
In addition making references to the Indiana Jones movies, various characters are wearing props that look like they are from the movies. Mac is wearing Indiana's hat, Charlie the leather jacket and Frank his famous bullwhip.
Frank makes reference to Raiders of the Lost Ark (with the bullwhip) and E. T. (when he hides among the stuffed animals). Both movies were directed by Steven Spielberg.
Mac's insistence on using a Swedish accent "because that's what Indy would do" is a reference to Indy using a fake accent in Indiana Jones and the Last Crusade (1989). However, in that film Indy was using a Scottish accent, since he was impersonating a Scottish lord.
