I love how Sunday Heathcliffs tend to be the worst of the week, even though they have the most space to be good.

In any case, Heathcliff dresses like Jabba the Hutt in an effort to eat the two or so birds living in the Bird Sanctuary (which I'm sure just has open gates to let the predators in). This measure promptly fails, though I'm willing to bet that it wasn't Jedi mind tricks that saw Heathcliff get defeated. Drunk on Jabba Juice, he imagines a worm talking to him in over sized word balloons, telling him that it is in fact the giant space-faring slug who gets the bird...and then a cat hangs from a screen door.
