One day, Carlos asked Jose: “I work just as long and hard as you do, but how do you bring home a suitcase full of $10 bills every day?”
“Look at your sign, what does it say?” replies Jose.
Carlos’ sign reads: “I have no work, a wife and six kids to support.”
Jose says: “no wonder you only get $2-3.”
‘Carlos says: “So what does your sign say then?”
Jose shows Carlos his sign – it reads: “I only need another $10 to move back to Mexico”
