I'll go ahead and throw another "math" blooper in here......it's in S7E6 "Anything You Can Do". At the end, the staff adds up the totals saying that the takings were 98 pounds, and the outgoings were 106.75 pounds.

This means the difference is 8.75. However, after they get done reporting the numbers, Mr. Goldberg says the difference is 8.45.

Funny, I would have thought that at least SOMEONE there on the set would have taken a moment to actually do the math - LOL.

Or maybe the writers did it on purpose to see how many would catch it.

Again, not so much a "blooper" but just a funny observation......in S6E3 "Do You Take This Man", they eventually have all the guests come up to the department floor via the elevator.

Hilariously, they all ride up in the lift together in one trip. After watching it a few times, it becomes very clear that there is a completely open wall in each elevator where people are coming from backstage, entering the lift, and then walking downstairs to the department floor.
