SORRY!

Eamonn: say sorry
Me: say sorry
Eamonn: sorry (apologetic voice) yay! I sorry! (claps hands)

He does this when he knows he should say sorry, but he's prompting us to tell him to say sorry.  It's pretty stinking adorable.  It's also part of his echolalia.  he will repeat "say sorry" repeatedly if I don't respond right away.
