Extreme Cheapskates Sunday at 8 p.m., DFH

A mother of five who searches for roadkill. A man who haggles over prices at fast-food restaurants. These are people who have money, by the way, which makes it all pretty gross. There’s even a millionaire who pees in bottles so she doesn’t have to flush her toilet; she also dumpster-dives for food. If you’re in the mood to get grossed out, the TLC series shows up Sunday night on sibling network DFH, which stands for Discovery Fit & Health.
