Easily the biggest news that came out of Wednesday's mass return to the airwaves by late-night's long-sidelined talk-show hosts was the unexpected appearance of David Letterman and Conan O'Brien's competing Strike Beards, a solidarity-signifying facial hair trend so hot that the clean-shaven visages of Jay Leno and Jimmy Kimmel now seem to indicate a conspicuous lack of support for the hosts' still-picketing writing staffs. (The embattled Carson Daly, we've been told, plans to smash his trusty Norelco electric shaver on his next show in an attempt to prove his commitment to the WGA cause, no matter how unflattering the resulting patchy growth may be.)

To help sort out the potentially confusing intersections of last night's bearded/unbearded and writer-having/writer-free developments in the brave new world of late-night TV (a situation complicated by Craig Ferguson's stunt-beard), Losanjealous has composed this handy Venn diagram, which should get you completely up to speed at a single glance.
