"... and didn't she have addition issues during the time period of the MTM show?"
Math problems? Like keeping up with the millions she was raking in with that dumb show?
Nah, it wasn't her *appearance* then that bothered me... it was the acting, the character & personality, which it seemed was probably a reasonable facsimile of the real MTM, and I didn't like it. Much like a toddler, what was 'cute' in Dick Van Dyke show wasn't when it matured more.
