Really?
Code:
[aia@arrow many]$ ls -l
total 0
[aia@arrow many]$ 
[aia@arrow many]$ find . -name "do_not_exit" -print0 | xargs rm
rm: missing operand
Try 'rm --help' for more information.
[aia@arrow many]$ find . -name "do_not_exit" -print0 | xargs

[aia@arrow many]$ find . -name "do_not_exit" -print0
[aia@arrow many]$
