When a smartass listens to the Podcast.

The differences between a blimp and a dirigible. A blimp is a hollow bag which is filled with hot hair. Passengers ride in a gondola attached to the bottom of the bag. A dirigible is a rigid airship in which the passengers ride inside the airship and it's filled with gas like hydrogen. Sorry and I will happy if someone points out my mistakes.

The problem with blimps is the stink generated by all that hot hair.
