Deja-Moo, the Two-Headed Calf at the Idaho State Museum

Tucked into the museum's Boomtown exhibit, in a setup styled like an old penny arcade, sits Deja-Moo: a real, taxidermied two-headed calf born in Gooding in 1950 and a museum fixture since 1951. It's a genuine preserved oddity hiding inside an otherwise straightforward state history museum. The penny-arcade staging makes stumbling onto it feel like discovering a sideshow relic.

The move: Pay the museum admission, beeline for Boomtown, and take a deadpan selfie with the two-headed calf.
