I was watching Columbo the other night - a completely bonkers episode called "Identity Crisis."

I stumbled on a Facebook post honoring all the typewriters appearing the series:

I cannot stress enough, though, how cuckoo this episode is. Patrick McGoohan cuts it up as you would expect. Add in Leslie Nielsen in his villian/badass era (he walks around a carnival with Patrick McGoohan with his shirt unbuttoned past his navel) and that's just for starters. I probably need to watch less t.v.
