About removing software.

I have some software that I want to take out but
apt-get remove or k-package cant find the software that I want to remove.

I can find the bin files by typing where is but these specific apps dont have any etc files.

In particular am talking about xeyes xlogo and some other stupid little programs like that.

If i just go ahead and delete the bin files will that cause a problem?

You can find out which package a file belongs to with :

dpkg -S file

example :
dpkg -S /usr/X11R6/bin/xeyes
xbase-clients: /usr/X11R6/bin/xeyes
