To be so actively recruited by a large law firm, Marshall would have had to graduated near the very top of his class, yet during the series he is portrayed as getting a number of "B" grades.
Ted, who is supposedly anti-gun, is wearing a Colt Peacemaker t-shirt.
Marshall is determined to work for an environmentalism organization, to save the planet and to do the ecologically correct thing. But then he gets seduced by an invitation to eat "Kobe lobster" - lobster which is fed with Kobe beef. Beef alone is extremely damaging the planet, this (hypothetical) decadency even more so.
