What is the episode that Lisa is not in?

Question

I was told that Lisa is the only Simpson that went through an entire episode without being seen or heard (except for the intro and couch gag (obviously))

Answer 1

I'm fairly sure Lisa has been in every episode. Bart on the other hand was missing in "Four Great Women and a Manicure".

Answer 2

There are two where she appears briefly but is silent, they are "Chief of Hearts" and "Moho House".
