Gravity

A sun walks into a black hole.
The black hole says to the sun "I don't think you understand the gravity of this situation".
There once was a fly on the wall,
I wonder why didn't it fall.
Because its feet stuck,
Or was it just luck,
Or does gravity miss things so small?
Even if there was no gravity, I'd still fall for you.
I got a C in Physics and my parents grounded me.
They say I don't understand the gravity of the situation.
An astronaut who normally fails on a weightlessness experiment, might surely be aware of the gravity of the situation.
An astronaut did a huge crime. He broke the law of gravity and hence, got a suspended sentence.
Have you found the center of gravity yet? It’s the letter v.
