Erin

Erin, voiced by Christina Ricci, is one of Lisa's four friends in "Summer of 4 Ft. 2". Lisa, tired of being an unpopular nerd, travels with her family to Little Pwagmattasquarmesettport with the intention of making new friends. While walking on a dock, she hears some teenagers and finds Ben, Dean, Erin and Rick. Acting like Bart, she immediately clicks with them and takes them skateboarding at the library. Her best friend in the group is Erin, who Lisa says is her first real friend. Bart discovers she's acting like him and decides to try to steal her friends. He shows them Lisa's yearbook (which has all of Lisa's nerdy accomplishments) and Lisa, assuming they won't like her any more, runs off crying. However, the group realizes Lisa is a good person and glue shells on the family car that say "Lisa Rules". They also sign her yearbook. It is unknown whether or not the group is from Little Pwagmattasquarmesettport or if they are also on holiday.
