As dedicated teacher (and later principal and college professor) George Feeny on "Boy Meets World," William Daniels has a devil of a time getting students including Cory (Ben Savage) and Eric (Will Friedle) to focus, but he does inspire the "Feeny Call," a shout that would draw the educator out of his house. When the show (1993-2000) signed off, he was the final character on screen and delivered the last line of dialogue: "I love you all. Class dismissed."

"Bueller? ... Bueller? ... Bueller?" That's the repeated query from an economics teacher played by Ben Stein, in the 1986 American teen coming-of-age comedy "Ferris Bueller's Day Off," written and directed by John Hughes.
