Join Mark, Jon and Jon as they traverse the M section of the Hitchhiker's Guide to the Galaxy.

Mice

Trillian - remember her? - kept some pet mice, who turned out to be the most intelligent beings on earth. We still don't know what species they are when they're not projecting themselves as little furry cratures with a cheese fixation.

Milliard Gargantubrain

Milliways

Milliways is the Restaurant at the End of the Universe. It was either built on the remains of Magrathea, or Frogstar World B, whichever you prefer.

A Bastablonian ad agency came up with the tagline "If you've done six impossible things this morning, why not round it off with breakfast at Milliways".

Mind zoo

Marvin was once the star exhibit of a mind zoo. He had to sit on a box and tell his story whilst people told him to cheer up and think positive.

For a long period of time there was much speculation and controversy about where the so-called “missing matter” of the Universe had got to. All over the Galaxy the science departments of all the major universities were acquiring more and more elaborate equipment to probe and search the hearts of distant galaxies, and then the very centre and the very edges of the whole Universe, but when eventually it was tracked down it turned out in fact to be all the stuff which the equipment had been packed in.

Multicorticoid Perspicutron Titan Muller

The Multi-corticoid Perspi-cutron Titan Muller is a super-computer of unspecified parameters and focus. Deep Thought calls it a cybernetic simpleton in comparison to itself.
