Artie Lange gave onlookers lessons on how to pick up one of the hot Las Vegas cocktail waitresses ... just sit and stare with your tongue out.

TMZ snapped this photo of Artie from "The Howard Stern Show" inside the Luxor Hotel and Casino this weekend, at the exact moment his tongue fell out of his face while staring at this hot young server. No word on if she accepted his dinner invitation.
