Hey, I Can Pee Outside in the Dark (S01E20)

Jake becomes a brooding musician when he continuously plays "Smoke on the Water" on his guitar with an ever-present grumpy attitude. In order to cheer him up, Alan tries a father/son chat, Charlie offers a jam session and Berta (recurring guest star Conchata Ferrell) just thinks the kid is constipated. Finally, Judith convinces Alan that Jake needs professional assistance, and they enlist the help of Dr. Linda Freeman (recurring guest star Jane Lynch). (Warner Bros. UK)
