Factual error: Their 'spot' for drinking is apparently in the French Quarter because of the street signs. That said, they are drinking Budvar beer. If you know about Budvar, it is the original Budweiser beer from the Czech Republic. Budweiser sued Budvar and won, preventing them from using the name 'Budweiser', even though Adolph Busch came up with 'Budweiser' after going to Pilsner, Czechoslovakia. Budweiser being the bully, and their lawyers and all, won the lawsuit. So now the beer is sold as 'Czechvar' in the US and 'Budvar' everywhere else, meaning they couldn't be drinking it in the USA.
Continuity mistake: When Ross is standing on the ladder working on the engine you see on the left side of the plane 7 skull decals. There are 4 on top and 3 underneath. The 3 underneath are at the back of the 4 decals. Then when the plane is taxiing on the runway the bottom 3 skull decals are at the front of the 4 decals. (01:17:30 - 01:19:35)
