A human cannonball comes to work at the circus one day.

And she finds that her cannon has been replaced with a bigger one. The ringmaster tells her that a more powerful cannon would please the crowd more.

So during the next act, she's fired from this cannon across the whole tent, and the crowd goes wild.

The next day, she finds an even bigger cannon. The ringmaster tells her that this cannon will be even more crowd pleasing.

So in the next act, she's fired across a field and the crowd goes wild.

The next day, she finds a truly humongous cannon. The ringmaster tells her that if the last cannon was good, then this one will be best of all.

So in the next act, she's fired over the horizon. When they found where she landed. She was badly injured.

When the ringmaster saw the hospital bill, he remarked "I guess I got too much bang for my buck."
