Thanks for the tip! I was hoping for Traveller-themed jokes, which I don't have, but I can supply my top-10 punchlines for IMTU Traveller jokes:
1. "...and so the android says, 'Well, how do you think the xenomorph got knock-kneed?'"
2. "...so the engineer was right: you *can* fit three reactor control rods in there – but it's a tight fit."
3. "...and the captain looks the android in the eye and says, 'Quick, go get my brown flight suit.'"
4. "... and the android says, "Well good. It's your turn in the cargo hold on Tuesday."
5. "...and the Zhodani says "It was okay I guess – but I didn't like the taste."
6. "...and the Vargr pilot looks at me and says 'Yeah, and that runway was a lot wider than I remember it, too."
7. “...and that’s how I found out that Droyne have three genders.”
8. "...and so the Vilani looks up and says, "That Vargr doesn't seem very shaggy to me."
9. "...and that's why you never let a Hiver handle the ship's finances."
10. "...so never order groat east of Regina, and that's why I'll never get another tattoo in the Spinward Marches".
