Getting Even - S4-E3
Factual error: Ash gives Albert a slip of paper with Lily's home address, including a postcode of WC2E. That postcode is in Central London, but the house Albert then goes to is somewhere far more suburban, a long way from WC2. (00:50:21 - 00:55:22)
Factual error: The guys supposedly stole $5million. The largest US bill is $100. This means there would be 50,000 bills. $5million weighs 110lb. They would not have got that into a guitar case, far less Albert being able to carry it that easily.
