Corrected entry: When Cleveland enters his house to look for money to repay the casino, he sees the College Fund jar and says "I can't do that to Ramona" but the step daughter's name is Roberta.
You're the Best Man, Cleveland Brown - S1-E21
Corrected entry: Cookie states to Freight Train that Cleveland is his only son. But in "Our Gang", we find out that Cleveland has a brother called Roderick. (00:09:40)
Correction: First, his name is Broderick. However, he's simply not LeVar's (Freight Train) son. Since Broderick and Cleveland have the same mother, they're still brothers.
Correction: Him calling her by a different name is a joke in the scene, not a mistake. It's intentional.
