If you can run the command as root, you can force the change to be accepted.
Example:
$ sudo passwd myusername
Changing password for user myusername.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
This is the perfect answer

Short answer: You can't.
work around:
change twice, e.g. old passwd is Bilbo1,
change to Frodo1 (from Bilbo1),
then change to Bilbo2 (from Frodo1).
why two changes ?
on the first change, Linux can only compare clear text Bilbo1 and Frodo1,
on second Linux can only compare Frodo1 and Bilbo2 (and all the crypted passwd, you can't revert to Bilbo1(*)).
This suppose you can change twice, which may have been disable by your system admin, to prevent such work arround.
Needless to say, do not use such a silly password.
(*) On second tought, I am not sure about this point in Linux.
