Marvels Less Mystifying

From Tardis Wiki, the free Doctor Who reference

Marvels Less Mystifying was a museum run by Benek Chaloupka in 23rd century Prague. His goal was to debunk magic, superstition and the occult.

When the museum became haunted by ghosts, Chaloupka commandeered the TARDIS, bringing the Third Doctor and Jo Grant to Prague in 2221 to help solve the mystery. (PROSE: Spoilsport)
