Feelings... Whoa, Whoa, Whoa - S11-E9

Character mistake: Cliff is convinced his neighbor is Hitler, but if Adolf Hitler were alive in 1991-2, he'd be over a hundred, and surely someone as knowledgeable as Cliff would know that. And even if he doesn't, Frasier should know that as well and correct him.

Comrades - S2-E4

Character mistake: Michael states that if you touch someone being tasered, you'll be tasered too. That's not true unless you touch them right between the probes. And in a later episode Michael's touching a man being tased with no ill effects.
