A big ugly Horc Barb walks into the Leaky Dingy and orders an ale, declaring "I'm the meanest toughest SOB in Stormreach, and I ain't paying for my drink! Pour me a free one barkeep!"
The barman looks the Barb up and down, then meekly pours him a pint.
Half way through his quaffing, a piece of magically animated asphalt strolls in to the bar, walks up to the Barb, lifts his drink right out from his hand, duly downs the Barbs ale, and walks out.
The Barb meekly says nothing, keenly examining his shoes throughout.
After the magically animated asphalt leaves, the barkeep says to the Barb "I thought you were so tough, but that asphalt just humiliated you and you did nothing?"
'Yeah", says the Barb, "I'm tough, but that guy... He's a total cycle path!"
