“The Curious Case of Jr. Working at the Stool” was seen by 5.597 million viewers

Cleveland Junior sits at a table with 6 empty beer bottles but when he busts the same table, there are 5 empty bottles.



And when he brings that tray (along with another) to Gus, there are only 3 beer bottles on the tray

When we see a close up shot of the box of crayons Gus puts on the bar, there's only one green crayon in the middle row, but when he says, “can you believe something so fun...”, there's two green crayons in the middle row, one he pulls out and another in the box.



Also...

The Peach crayon Cleveland Jr. is using changes color from a lighter color to a darker color after Gus says, “Does every bar know about this?” and Cleveland Jr. says “I don't know”

When the guys are at the Broken Stool after Cleveland gets his fake mustache, there are 16 bottles of beer in the scene, 12 bottles on the table (& 4 on the floor).
Gus brings 4 more, making 16 on the table, (20 in all).



However when the guys start to fight there are 13 bottles on the table



but when the shot widens, there are 10 on the table.
