True true.


There should be a "-" by the 5 for the joke to work.


It's still funny as hell.

Why can't we just flip it and call it 8 - x and 5 - x?

The funny thing is, the first expression here, strictly speaking:

is wrong.

Yup, the 5 on the right hand side of the = is upside down.
Rotate it 180 degrees.

Seriously,
limit as x approaches 5 from the left (-) = negative infinity.
limit as x approaches 5 from the right (+) = positive infinity.
Asymptote at x = 5.

Close, but the real quote is that the LOVE of money is the root of all evil.

The lack of money is the root of all evil.

And I would add, the lack of women wouldn't be much better.
