In one shot, Choo Choo is at the pool table. A couple shots later, TC is at the same spot. We do not see TC or Choo Choo moving.
When Pierre "shoots" TC, Goldie runs up to confront Pierre. A couple shots later, Goldie is next to Spook.
When TC finds out that the guns were loaded with real bullets, we see a bullet hole in his hat. Pierre did not shoot TC in the head. TC was shot near the heart.
When Choo Choo is mourning TC's "death," he is holding Goldie's hand. In the next shot, Choo Choo is obviously not holding anything. A couple of shots later, we see that Goldie is not even next to Choo Choo.
On one of the gang's attempts to send love to Choo Choo's girlfriend, they push too hard and Brain goes through the road, a normal cliche. The road, however, should have been too hard for Brain to go through.
