Sparky is the salty boss, when the over-eager new guy comes in.

Watch the tails and the feet.  Rusty comes in with a big idea.  His tail is wagging like mad, but his shifty feet show that he isn’t sure how the boss is going to like it.

The boss is busy licking something and doesn’t want to be disturbed.  Sparky’s tail is straight out in the, “I’m not dicking around” position.  His front paws are planted.

After he lashes into Rusty, notice how Sparky’s tail wags happy in the end.
