 Even in this short feature theres plenty of side references. For  example, Donkeys line "We got a donkey driving a carriage made from  an onion, its dark, and our horse are wearing sunglasses. Hit it,  boys!" is a quote from _Blues Brothers, The (1980)_ (qv), and  shortly after that he says "I feel dead people", reference to a  quote from _Sixth Sense, The (1999)_ (qv) stating "I see dead  people".
