4x1 - Red vs. Blue

Grif is still despairing over being back in Blood Gulch, despite the others' attempts to shut him up. Meanwhile, back at Zanzibar, Tex, Tucker, and Caboose discover that Church is back in ghost form again. Church explains that he was literally scared out of his body after being ambushed by the Alien in the last episode, though his attempts to explain this are repeatedly interrupted by Caboose's stupidity and Tucker's attempt to hijack the flashback and showcase his sexual fantasies; Tucker wisely ends quickly so as to avoid getting his head blown off by Tex. Tucker uses the catch phrase "Bow-chicka-bow-wow" in this episode for the first time, much to Church's annoyance.
