A nun is standing outside a pub

A nun is standing outside a pub and a man comes round the corner, planning to grab an after-work bevy. The nun immediately points at him, and intones:

"Before you enter this den of sin and debauchery, think of your mother and father!"

The man wipes away a tear, and says "They're dead, God bless 'em. They're dead, in heaven."

"Well," says the nun, "Then think of the damage the alcohol will do to your brain!"

"What? What are you talking about?" the man asks. "Have you ever had a drink?" The nun says she has not. "Then how can you talk to me about alcohol? I'll tell you what I'll do," he continues, "I'll buy you a drink, and after you've drunk it, then you can talk to me about alcohol. What'll you have?"

"I don't know," says the nun. "What do ladies usually drink?"

"Gin," he replies.

"Oh, alright," she says. "But - but can you put it in a cup, so nobody notices." The man nods and walks into the bar, calling out to the bartender.

"Bartender! I'll have a beer, and a double gin in a cup!"

"It's that bloody nun outside again, isn't it?"

Eugen Langen

Died 2 Oct 1895 at age 61 (born 9 Oct 1833).German engineer who pioneered in building internal-combustion engines. In 1866 Eugen Langen, who owned a a sugar refining company, financed Nikolaus August Otto (1832-91), developed a more efficient gas engine. The Otto & Langen company produced stationary gas engines (usually powered by coal gas). Otto went on to build, in 1876, the prototype of the so-called Otto-cycle engines used in most modern automobiles, fueled primarily with gasoline, alcohol or benzene. Langen also devised the Wuppertaler suspension railway which opened in 1901. His Schwebebahn (swinging railway) has operated successfully along the Wupper river for almost 100 years. It has survived two world wars and continues to operate profitably and safely today.
