“I’ll have a café mocha vodka Valium latte to go, please” is a jocular order (combining various popular daily infusions) that has been printed on many images. “I’ll have a cafe mocha vodka Valium latte to go, please!” was printed in the Asheville (NC) Citizen-Times on October 28, 2007. The order probably originated on an image.
       
“Needs one large mocha Prozac vodka latte, complete with whipped cream and Valium sprinkles” is another drink combination.

In the center sits a cup of steaming coffee with the caption, “I’ll have a cafe mocha vodka Valium latte to go, please!”
 
Every afternoon I read that napkin aloud for my co-workers, and without fail, we laugh, and stress bombs defuse.

Kitchen Gourmet
7700 West Arrowhead Towne Center, Glendale
You don’t have to be a serious cook to appreciate this quirky kitchen store (also part gift shop) in Arrowhead Mall. You’ll get a kick out of the goofy signs at Kitchen Gourmet (“I’ll have a chocolate mocha-vodka-Valium-latte, please.”), the hideous Elvis-headed cookie jar and the Day of the Dead-themed knickknacks.
