FunnyOrDie.com

A YouTube alternative for an in-crowd of comedians and actors, Funny Or Die features the likes of Jimmy Fallon crooning "Car Wash for Peace" ("put down those guns, pick up a sponge...") and Ed Helms as Glen the Zombie-American. There's also some odd and amusing stuff from Will Ferrell, who launched the site with writers Adam McKay (Talladega Nights) and Chris Henchy (Entourage) and plugs his personal faves on the home page. Don't miss David Blaine Street Magic 2 (it's a tad too long, but it pays off) or Barats & Bereta's Fast Food Commercial (gross, but good).

AtomFilms, offers its own extensive comedy library, which registered members can view in higher resolution on a full screen. Access is free, but the trade-off is ads, ads and more ads. Has The Onion's new video site left you cold? Try This Just In ..., a news-parody site produced by HBO in partnership with AOL (corporate cousins of Time.com). And 23/6, due to launch any day, has been conceived by the folks behind The Huffington Post and partner IAC/InterActiveCorp (owner of CollegeHumor.com, where we caught the brilliant movie-trailer mashup "V for Dodgeball") promises more riffing on current events and pop culture.
