The Chronicle recently interviewed the owner of Three Twins Ice Cream in the Lower Haight, who happens to make the world's most expensive (but not delicious—that title belongs to Mitchell's) sundae:

Q: So what's the deal with the $3,333.33 banana split you have on the Napa store's menu? Are you out of your mind?
A: I put it up not really as a joke, but for something fun for people to read while they're waiting in line.

I really hate the most expensive (dot dot dot) when most of the expense is for the serving dish, like the most expensive cocktail that comes in a crystal chalice. We serve the most expensive sundae, but the food cost is one-third of the price. It's three scoops of organic ice cream; a banana, organic of course; and is topped with three syrups made from three extremely rare dessert wines - a 1960s vintage Port, a Chateau D'Yquem and a German Trockenbeerenauslese. It also comes with a cellist who will play anything you want while you eat the sundae.

Be sure to wear your “I'm part of the 1 percent” card on your chest when you order it.

Q: You say the banana split is the world's most expensive sundae. Are you sure it's the most expensive?
A: Absolutely. We researched it extensively on the Internet.

Pssh.  While all this might be a tad out of my league, I CHALLENGE your claim that a 20-scoop sundae served from a KFC bucket or whatever is “absurd.”  And I'm sure it tastes wonderful doused in Boone's Farm.
