hostkey

I usually end up deleting the entire known_hosts file, which I have no problems for. But just out of curiosity, Is it possible to remove just a single entry? I opened the known_hosts file, and other han understanding that the file contains fingerprints for a given machine, I dont understand anything. Below is the message I faced, which led me to ask this question.

Add correct host key in /home/wissen16/.ssh/known_hosts to get rid of this message.
Offending key in /home/wissen16/.ssh/known_hosts:1
RSA host key for foo.com has changed and you have requested strict checking.
Host key verification failed.

Thanks.
