Bill walks into a bar located on the roof terrace of a skyscraper in downtown Metropolis.
Bill’s standing at the counter waiting to be served, when the guy next to him offers him a sip of his cocktail.
“Take a sip of this cocktail buddy,” the guy says, slurring his words. “It’s a special drink and it will give you the power of flight.”
“Oh, that’s got to be nonsense,” says Bill. “There’s no way taking a sip of someone’s drink will have me flying around the rooftops of Metropolis.”
“Would I lie to you?” the guy says to Bill. “Let me show you.”
With that, the guy swallows the contents of the glass, then jumps off the roof, flies around in a wide circle and then glides smoothly back onto the roof terrace.
Bill is amazed by what he’s just witnessed. So he says to the bartender, “I’ll have whatever he’s been drinking.”
Bill is served the same cocktail which he swallows in one and then he attempts to jump off the roof but falls flat on his face on the edge of the roof terrace.
The bartender looks at the guy who’d encouraged Bill to try the cocktail and says, “Dammit, you really are a nuisance to other customers when you’re drunk Superman.”
