Cougars is yet another sublime example of 30 Rock's ability to turn any silly premise into comedy gold. Of course, it helps a lot when the characters it uses are every bit as silly as the story. In this case, that character is the wonderfully moronic, porn-obsessed Frank, played to ridiculous perfection by Judah Friedlander.
His involvement in the plot line is directly linked to the main story, which focuses on Liz becoming a "cougar", i.e. a woman who dates younger guys, and hooking up with the way too young Jamie, who's so good-looking the normally straight Frank claims to be "gay for Jamie". While the situation escalates hilariously, Jack and Kenneth make the terrible decision to help Tracy with his youth baseball team, which leads to Jack turning into a despotic coach.
The almost militaristic version of Jack seen in this episode is once again proof of the fact that Baldwin's Emmy win for the second season was fully deserved (although his full-on insanity in Rosemary's Baby remains unrivaled), and any scene with either him and Jack McBrayer or him and Tracy Morgan (plus Tina Fey, obviously) is a foolproof recipe for memorable laughs. All in all, though, Cougars belongs largely to Friedlander, whose odd-ball line delivery has always been a guaranteed success. Here, he goes all the way when Frank tells Jamie their situation is "a Sam and Diane thing". Now, he may not be Ted Danson (it's doubtful he'd compare himself to Diane) at least not physically, but man, does he get close in that scene. Which reminds me: when can we expect a cast-member of either Cheers or Frasier to make an appearance, given Seinfeld, Friends and Will & Grace have already contributed with their share?
