"MASH" Refrences on The Simpsons

Lisa's First Word (Season four).

There's a scene in a flashback in which Marge asks her frienRAB if they've seen the last episode on that show.

Hi,

Does anyone know any MASH (70's T.V. Show) refrences on the Simpsons. If so, can you tell me what episodes they are on? Thanks.
