Recurring character
Sometimes a recurring character from one show appears on another show , such as when Dave Thomas and Rick Moranis hosted "Saturday Night Live" in 1983 and portrayed Bob and Doug MacKenzie , or when Emily Litella ( portrayed by Gilda Radner ) from "Saturday Night Live" appeared on "The Muppet Show" in 1978 . Sacha Baron Cohen's character Ali G is another example , originating on the Channel Four series "The Eleven O'Clock Show" . The character was such a huge success that Cohen got his own show as the original show was cancelled .
