"You can patronize the slots till Doomsday or buy any number of scratch-off tickets and never gain any significant winnings, but then just as soon as you stop playing, the very next player will win big."
Many an addicted gamer believes in Murphy's Law of Gambling, even though it is indeed :"all chance" and thus seldom actually works out that way.

"You can heave and strain on da wrench till Doomsday and never get a stubborn bolt loosened, but then just as soon as you ask a stronger --- and probably very busy himself --- person to come and help, DAT'S when da blasted bolt actually WILL yield, either when you give a final demonstrative yank on da wrench to show da second person how supposedly stuck da bolt is, or when he himself hauls back on da wrench and said previously-cranky bolt unscrews with little effort on his part, indicating dat your OWN last tug actually HAD cracked it free after all, and so if you had 'just given it one more go' yourself, you actually COULD have gotten da bolt out on your own, without having to interrupt your now-ears-smokingly-annoyed-at-being-needlessly-called-away colleague in da first place."
I wonder if da inventor of da impact wrench had originally felt prompted to do so due to his having frequently encountered Murphy's Law of Bolt-Loosening???

If you order just one of said tasty sandwiches, you will still feel hungry afterwards, but if you ask for two of them, you will only be able to finish one, and so you'll hafta just refrigerate da second one for later.
Having a friend treat you to lunch is a classic occasion for Murphy's law of footlong-subs to pounce and embarrass you. One simple and sensible way to avoid this face-reddening situation would be if your friend both has a smaller appetite than you and likes a lot of da same kinds of filling-ingredients; in dat case, you could just order two sandwiches, eat one, have your friend consume his fill of da other one, and then give da rest to you to finish along wif your own.

Noun. When a man is set up to be robbed, the victim thinks he is going to meet a woman. Typically done when a woman sets up a man, asking him to come over, but another man or group shows up to rob him. More rarely, a man will catfish another man by pretending to be an attractive or easy woman to get a man's address or get that man to come to a sketchy location. Not a scam, this is always done in person.
