Heidi was just more enthusiastic, funnier and just more fun! :D

Lisa had virtually no personality, in my opinion...Heidi had beauty AND brains.

I agree, Heidi/Debbie had more brains and beauty. Lisa/Pamela almost seemed bored and uninterested with the role, and appeared to only want to be a lead role.

Well I find it UNBELIEVABLE that Pamela Anderson would be hired for a reason other than her brains.

I would just to say that if Pamela Anderson was waiting for her career to take off on Home Improvement, then she literally is the dumbest blonde ever. And to prove she was, she ended up doing a show that she didn't need brains, she just had to sit in a lifeguard chair and get hit on by David Hasselhoff(spelling error, sorry) Heidi is so much better, she's so much more gorgeous and she def liked being the tool girl more and people liked her so much better. Obviously. My props go to Debbe Dunning.

I met Debbe Dunning in person, she is not only gorgeous, she is very friendly, not a Hollywood snob by any means, very down to Earth.

Heidi, Heidi, Heidi!
