** David Winn replaced Rhode Montijo as both Lumpy and Splendid when Rhode left the show. Similarly, Kenn Navarro replaced Mark Giambruno as both Lifty and Shifty (although Giambruno's laughs were sampled in at least one episode) and Francis Carr replaced Jeff Biancalana as Russell.
** Kenn Navarro voiced Handy in "A Hole Lotta Love" because Warren Graff was unavailable.
