Is it normal to look like mr potato head

I'm 58 years old and until recently no-one ever told me I look anything but normal, at least to my face. But about a year ago when I took a new job, my workmates took to calling me Mr Potato Head because they say I resemble him uncannily. Weirdly enough, when I went on vacation over Christmas, there were some kids who were in the same hotel as me and I heard them snickering and pointing me out to their parents as Mr Potato Head. Okay, so I'm kinda bulky, I wear spectacles and a hat and I have a small moustache, also I have some pockmarking on my face because of acne in my teens, but when I look in the mirror I don't see anyone who looks like Potato Head looking back at me. For a start, I don't have brown skin and my head ain't out of proportion to my body. But when I went in to work today, someone had wrote 'Mr Potato Head' on my locker door, so I guess I do look like the guy after all, even though I can't see it myself. Is it normal to look like Mr Potato Head? I mean, are there loads of people out there who look like him? And how the hell do I get folk to stop calling me Potato Head? I've got no ladyfriend right now and if that's because I look like Mr Potato Head, I need to know what to do about it. Anyone?
