I'm not that old, but I remeber Debbie Dunning replacing Pam Anderson on Home Improvement. Debbie fit the cute girl that might know a bit about tools way better than Pam did. Debbie is still looks just as good today as she did then.
Wiig gets laughs out of me, no matter what she does. The Target lady, the sketch with Amy Adams where they were twins, etc. MacGruber rules, if for no other reason than the episode with McGuyver. Abby Elliot as Angelina Jolie was classic.
