I am the same, I wouldn't recognise half of these American tv personalities/sports players. I would recognise movie stars if they weren't too disguised though!
I maintain that my Mum bumped into Meg Ryan at Downtown Disney in
Disneyland CA, in Dept 56. Mum asked her what a "votive" was (as it was not a common term over here at the time). She seemed very nice and just a regular person, but both my sister and I both independently thought she looked heck of a like Meg Ryan but with longer hair.
Well, shortly after our return we saw pictures of Meg Ryan in a magazine or online and she was sporting longer hair than usual, so that really convinced me that it was really her!
Did I mention my Mum also accidentally poked this lady's head with an ornament when in the queue to pay at the same store??? heheheh, how embarrassing!
