I am totally not trying to explain this joke — especially since the link to the original joke is broken.

That said : well done, BASA!

Transcript:

Mr and Mrs Bugg stand to one side of a rocket launch pad. The tower is still connected to the rocket, a huge affair with BASA written down the side, and an antennae’d capsule on top. You can just about make out the face of the astrobugg in the window of the capsule.

The text reads: “Novembug 14, 1969: BASA launches Apolbug 12, the second Bugg mission to the moon without calling for help.”
