While they weren't that many in the Happy Days(unless you count Joanie Loves Chachi), they seem to have terrific chemistry between them. It is always interesting that she co-starred four times(Happy Days, Joanie Loves Chachi, Charles In Charge, and a fairly recent independent movie she did in 2001) with Scott Baio. I know it is acting that they are doing, but it kind of touching watching them banter off each other like that.

I agree. They were a great mother/son team.
