"La Lotería" is El Fantasma giving the lazy a piece of his mind, ranchero style. The title line is the whole argument in one joke: "Si quieren la lotería, mínimo el boleto compren" (if you want to win the lottery, at least buy the ticket). The people he is aiming at are "ahí de sentadotes" (just sitting around), sentadote being sentado (sitting) blown up with the suffix -ote to make it bigger and lazier, waiting for luck to knock on the door.
He opens with a ranch proverb: "Qué ladradas pega el perro cuando se le mira de lejos el hambre" (how loud the dog barks when you can see its hunger from far away), meaning the ones who make the most noise are the ones with nothing. His own life is the counterexample: he gets up at six so that at home "no falte chuleta" (there is never a shortage of pork chops), and he is not envious of what anyone else has. The weather chorus is lovely and practical: "Del cielo nomás la lluvia" (only rain falls from the sky), and even though the sun comes out for everyone, "no a todos les gusta quemarse la nuca" (not everyone likes getting the back of their neck burnt), which is his way of saying not everyone wants to work outdoors and sweat for it.
Watch out for the Mexican slang. Chingón in "Vieran qué chingón se siente" (you should see how damn good it feels) is a vulgar but very common word for awesome, and huevones is a rude word for lazy people. Nomás is the Mexican way to say solo (just), and chequen el dato means "check out the facts". The verse about not looking for trouble, "pero si me encuentran, tampoco le saco" (but if it finds me, I won't back away from it either), is classic corrido bravado, and he closes by saying he has handed out his three pieces of advice.
