If you could own one original Simpsons cel which would it be?

If you could own one signed and certified authentic cel from any Simpsons episode ever what would it be? For me, it would have to be the cel of Homer sitting on top of his car looking at the stars from S7E8 Mother Simpson.

Also in CLOSE second would be the cel of Bart’s heart getting ripped out in S4E8 New Kid on the Block… you won’t be needing this!
