Funny easter eggs

I really like to know about funny easter eggs in software, specially if they are in command-line tools/apps. I've posted some before (sorry, but I won't bother searching them just to link), but today I just found about one other:

root@noori ~]# python
Python 2.4.3 (#1, Jun 13 2006, 16:41:18)
[GCC 4.0.2 20051125 (Red Hat 4.0.2-8)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from __future__ import braces
  File "", line 1
SyntaxError: not a chance
>>>

Thanks to Melo for this one...
