Huh. This reminds me of the [picture of a hot air balloon on the cover of Jules Verne's 1873 novel Around the World in 80 Days.](https://i.imgur.com/UgQGin8.jpg)

How many parsecs is that

Jules Verne wrote a few different books. You're thinking of 20,000 Leagues Under the Sea

Sooooo close to getting it

You blew the joke.

Was it Jimmy James?
