snort (one's) Sprite

Sharing laughs at the meal table is always a potentially dangerous proposition. Laughing while drinking invariably causes whatever you're drinking to be sprayed across the table. One memorable night at the Posh Denny's, Nutation managed to get Ira (normally fairly unflappable) to snort his Sprite not once, but twice. Once, with the Jenny Crank Diet anecdote, and then again later with the fudge pachyderms joke.
