Two light stories are making the rounds: a 1,900-calorie milkshake drawing a government scolding, and a British choir that welcomes bad singers.

• Shake Shack's new Reese's peanut butter cup shake packs 1,900 calories in one cup.
• It is built from vanilla frozen custard, peanut butter and fudge sauce, a hard chocolate shell, whipped cream, and two kinds of Reese's candy on top.
• The Department of Health and Human Services took notice and jokingly told customers to skip it.
• In Britain, the Off-Key Choir draws 80 members who sing together every week with no talent required.
• Its founder put out an ad eight years ago asking for people who could not sing, and 55 showed up.

Outlook: Expect the shake to stay a limited-time curiosity and the choir to keep growing on the strength of not caring how it sounds.
