Using only the magnetic letters stuck to my refrigerator, we were able to discover these promising, yet unregistered domain names!
lisp.tv (imagine the media empire that could be built around that!)
QykDr.com (quick doctor)
And venturing beyond the refrigerator, we also found these gems:
un4tun8.com (I went ahead and registered this one)
grrrrrrrr8.com (that has eight 'r's)
There's a goldmine in replacing 'for' with '4' and 'ate' with 8.
Don't limit yourself to good ideas...
