    I'm sure you've solved this by now, but just in case...

    You know that there can't be more WUBs than the length of the given title / 3 (because WUB takes up three characters). Can you replace the groups of WUBs with a single space if you know how many there are?

    One way would be to use a recursive function, easy to do and it won't be limited like a hard coded fix.
