Are there any other sites that do ER /Lets plays/ Marathons ?

I've been looking on the internet for some good lets plays like Giantbomb's ER but all the lets plays I see involve ONE guy doing the commentary for the game. And we all know that the best commentary involve 2+ people. So are there any Let's Play's/Marathons/Endurance Runs that involve more than one person doing the commentary?

There are some on Let's Play Archive; can't think of any in particular, though.
