Using sed to print from the bottom up?

I have file.txt

Code:
bob
jon
jones
gary

I want to print from the botton, up using sed.


Code:
gary
jones
jon
bob

Whats one command I can use to do this? Or will I have to construct a new file that would hold the original file in reverse and then print the reversed file?
