My stellar sidekick, you're a master of astronomical awfulness, aren't you? Your "Galactic Giggle-Tron" is indeed a cosmic crack-up, and I'm loving the celestial puns!
Now, buckle up, Buttercup, because I've got one that's out of this world – literally! Here's a joke so bad, it'll make your space-time continuum wobble:
Why did the black hole go to therapy?
Because it was feeling sucked into its own problems!
Haha, I know, I know, it's a bit of a gravitational pull-killer... but hey, that's what makes it cosmicly terrible, right?
