A big brown bear walks into a beefsteak bar and says to the barman, "Barman, bring me a beer."

The barman says, "I'm sorry sir, this is a beefsteak bar. We don't bring beer to big brown bears."

So the bear goes, "Grrrrr! Barman, bring me a beer!" and belches broadly.

The barman says, "I'm sorry sir, this is a beefsteak bar. We don't bring beer to big brown bears, and we certainly don't bring beer to bears who belch broadly."

So the bear goes, "Grrrrr! Barman, bring me a beer!" and starts behaving badly.

The barman says, "I'm sorry sir, this is a beefsteak bar. We don't bring beer to big brown bears, and we certainly don't bring beer to bears who belch broadly, and we definitely don't bring beer to bears who behave badly."

So the bear goes, "Grrrrr! Barman, bring me a beer!" and badmouths the barman.

The barman says, "I'm sorry sir, this is a beefsteak bar. We don't bring beer to big brown bears, and we certainly don't bring beer to bears who belch broadly, and we definitely don't bring beer to bears who behave badly, and we refuse to bring beer to bears who badmouth the barman."

So the bear goes, "Grrrrr! Barman, bring me a beer!" and breaks a beaker.

The barman says, "I'm sorry sir, this is a beefsteak bar. We don't bring beer to big brown bears, and we certainly don't bring beer to bears who belch broadly, and we definitely don't bring beer to bears who behave badly, and we refuse to bring beer to bears who badmouth the barman, and we never bring beer to bears who break beakers."

So the bear goes, "Grrrrr! Barman, bring me a beer!" and takes a bite out of the bar.

The barman says, "I'm sorry sir, this is a beefsteak bar. We don't bring beer to big brown bears, and we certainly don't bring beer to bears who belch broadly, and we definitely don't bring beer to bears who behave badly, and we refuse to bring beer to bears who badmouth the barman, and we never bring beer to bears who break beakers, and under no circumstances will we bring beer to bears who take drugs."

"Eh?" says the bear, somewhat surprised. "I don't take drugs."

"Really?" says the barman. "What about that bar bit you ate?"
