Cinco = Sounds like a stereotypical Mexican name but its pronounced like sink-o and you sink in quicksand.
That's about as best I can explain it.
Oh... yeah, I'm Mexican, so, I found it dumb that I couldn't figure out a joke about us.
Anyway... I think I won't be making more jokes. I'm sorry if anyone felt insulted by my jokes. Maybe best thing will be to close this thread...
