Is there a surname that you personally detest?

In my half-lifetime,
I've strangely kept running into bad luck with people
who have the surname 'Im';;
Not just men,
but even women...
Even looking back to my school days,
the lackeys of the bullies and delinquents often had the surname Im,
and in my company or in society,
the 'Ims' around me always seem to reek of being frauds...
So personally,
when someone introduces me to a person
and I hear that their surname is Im,
I can't help but develop a prejudice immediately.
