Fridge / Columbo S 01 E 01

Fridge Brilliance:

• Ken pitches the notion that The Mafia killed Jim, but Columbo points out several holes in the plan and clearly only pretends to be convinced by Ken's theory. Well, of course it's a flimsy idea—Ken's not a writer (or at the very least, he's a lousy one). Leaving aside an inability to think of something less clichéd, a writer worth their salt would research the methods of a hit man before spinning a story about one.
