"La Quinta."

Spanish, for either
"The Fifth One"
or "The Villa" ("Country House")

But according to the La Quinta Website,

It means "free high-speed Internet."

Wouldn't you think it really stupid if you saw an ad for a hotel in Spain which advertised

And according to a banner ad I saw while building this page

"La Quinta" also translates into "Win Sirius for Life."

Big thanks to good friend and Dumb Ads reader Steve Hedenskög, for knowing stupid when he sees it, and forwarding it to me.
