A version of a popular joke with a Libertarian twist:
Three colleagues, a Democrat, a Republican, and a Libertarian went out to dinner. And the Libertarian, against his normal instincts, allowed the others to talk him into splitting the dinner tab equally. Doing his part to help keep the bill down, the Libertarian ordered the $9.99 dinner special and a sparkling water. The Republican had a Scotch on the rocks and the Democrat had a vodka and tonic before dinner, and the Republican ordered the $29.99 sirloin steak while the Democrat had the $34.99 lobster dinner. Then both the Democrat and Republican had an after-dinner liqueur at $5.99 each, while the Libertarian had a cup of coffee. The check came to over $100 — over $125 with tax and tip.
However, to add insult to injury, about the time the waiter brought the check, the Democrat got a call on his cellphone and had to step outside to talk. And the Republican looked at his watch, said he was late for an appointment, excused himself, and hurriedly left.
When the Libertarian protested at being left to pay the entire bill, which he had to put on his credit card to cover, the Republican said: "But I saved you money by spending five dollars less than the Democrat." And the Democrat said: "You can't blame me for the high bill, because the Republican spent over $40 all on his own!"
Which probably makes the Libertarian hope that the other two don't use a colon cleanser so perhaps the Libertarian will live longer and healthier, or at least be around longer to pay off the credit card debt from the other two.
