You can create any arbitrary address simply by putting the correct checksum at the end. You, of course, will not know the secret key, so anything that is sent there is unlikely to ever be received will be destroyed and can never be spent.
FIFY.
Here is an example I made a long time ago:
11When1DieBuryMeDeepLayTwoXVEY5jv - (Unspent) 0.00000001 BTC
11SpeakersAtMyFeetAPairofXXTyrHor - (Unspent) 0.00000001 BTC
11HeadphonesonMyHeadAndXXXXYUSvnd - (Unspent) 0.00000001 BTC
11ALwaysPLayTheGratefuLDeadWdq4Xo - (Unspent) 0.00000001 BTC
How do you add a check sum? Might come in handy later.
