Marge is able to split her hairdo in two? Frink had fish in his platform shoes? Milhouse's parents seemed to be together at Artie Ziff's prom? I wonder how much Ziff had to pay them for *that*.
The inevitable "Where's Springfield?" debate
Marge points out that West Springfield is three times the size of Texas. Compared to the size of Springfield itself on the map in Act 3, Springfield would seem to be quite large. Too large for Krusty to take Lisa to West Springfield Elementary in "Trilogy of Error".
Also, the river south of West Springfield bears a slight resemblance to the flow of the Rio Grande, if you presume that the map has north at the top.
