Here, the critically acclaimed 2005 romance drama, Brokeback Mountain, starring Heath Ledger and Jake Gyllenhaal, is comically referred to in a cut-away gag where Brian is handed a copy of a film about "Brokeback Mountain, from the point of view of the horses". One of the horses pops its head into Ennis and Jack's tent to see if they're still sleeping, but they're getting up to "other activities", spooking the horse and causing it to run off.
