"Chief wants beer!" joke

An American-Indian walks into a saloon with a shotgun in one hand and a 10-litre bucket of manure in the other.
The Indian says to the bartender,
"Me want Lager!"
The bartender says, "Sure, Chief, coming right up."
He then serves the Indian a
tall glass of Tennents Lager.
The Indian drinks it down in one gulp, picks up the bucket, throws the manure into the air and blasts it with the shotgun. He then walks out.
Five days later, the Indian returns. He has his shotgun in one hand and another bucket of manure in the other.
He struts up to the bar and tells the bartender, "Me want beer!"
The bartender says, "Whoa there Chief, we're still cleaning up from the last time you were here... What was that all
about, anyway?" he asked.
The Indian explained, "Me training for job as government employee. Drink beer, shoot the shit, disappear for a few days, then
come back and see if somebody else has cleaned up the mess me left behind... "
