It was impossible to determine Pat’s gender, but that never stopped people from trying to guess, and surprisingly, the rather simple punchline never got old.
Mary Katherine Gallagher – Molly Shannon (1994 – 2001)
Mary Katherine Gallagher was a nerdy Catholic school girl who would stick her hands in her armpits and then smell them when she was nervous. Which was most of the time. She was often fond of flashing her underwear while doing spastic splits and cartwheels.
Arianna, The Spartan Cheerleaders – Cheri Oteri (1995 – 2000)
Cheerleaders aren’t usually that funny. But The Spartans were different. Arianna and Craig (Will Ferrell) were a pair of cheerleaders who didn’t make their school’s squad, so they started their own — and stuck to C-list sporting events, like chess tournaments and swim meets.
Margaret Jo McCullen – Ana Gasteyer (1996 – 2002)
Margaret-Jo McCullen was always our favorite half of The Delicious Dish team, and as it turns out, the soft-spoken character was one that Ana Gasteyer created with fellow comedienne Leslie Newton back when she was a member of The Groundlings.
Debbie Downer – Rachel Dratch (1999 – 2006)
In Rachel Dratch’s Debbie we found an unlikely hero: someone who was brave enough to give a face to the feline AIDS crisis.
Whitney Houston – Maya Rudolph (2000-2007)
During her seven-season run on SNL, Maya Rudolph was the master of celebrity impersonations — from Oprah to Beyonce to Donatella Versace — but our favorite has to be her over-the-top take on poor, cracked out Whitney Houston.
Dakota Fanning – Amy Poehler (2001-2010)
Amy Poehler was the first female cast member promoted from featured player to full cast member in her first season on the show. Her Dakota Fanning series was an instant classic, perfectly encapsulating the precocious weirdness of the young Hollywood actress.
Gov. Sarah Palin – Tina Fey (2000 – 2006)
Tina Fey won an Emmy for best guest performance in a comedy series last year thanks to her freakishly spot-on imitation of Sarah Palin; her repeated appearances on the show helped jump start sluggish ratings and the sketch above became NBC.com’s most-watched viral video ever.
