When Bugs sets the cup down, it's in front of him, but in the next shot, the cup is somehow further away from him.
When Bugs, "I'm not going to drink till you drink yours first", the cup is far away from Yosemite Sam. Before Yosemite Sam says, "It's a deal", the cup is close to him.
When Bugs Bunny cuts a hole through Yosemite Sam's floor boards, he goes through a bear skin rug and emerges through the bear's mouth. The mouth closes on Bug's midsection, causing bugs to panic. He tries to escape the bear's mouth and drags the rug away. But the hole in the floor through which Bugs emerged is no longer there.
When Bugs and Sam first go to bed, the far view of Sam shows his boots on the floor near the bed. When the view jumps closer, his boots are gone.
Before Bugs drinks his carrot juice (in the wide shot), his chair is close to the table. When the view shifts to a close-up and Bugs reaches for his juice, he is sitting much farther away.
