Mike calling the black repairman's assistant an Uncle Tom
Ok Mike came off extremely racist in the episode where they was each telling their own version of the repairmen coming to fix the refrigerator. So apparently in Mike's mind the black repairman's helper was some goofy Uncle Tom behaving like some over the top stereotype. But in realty he was just a normal dude that didn't act like some whipped Uncle Tom.
We expect the racism from Archie but in this episode Mike making the black guy out to be so goofy and calling him an Uncle Tom after we saw the black guy was actually a pretty normal dude that didn't let anyone run over him, it just made Mike look like a liar and a racist.
