What he really means: I have to say I don't know what he was trying to convince me of here - he threw his parents under the bus for hating his wife.
If he really meant it he would have said: Nothing. It's none of my business.
Whatever happened to Lurch? And his equally attractive wife Bertha? After being fired from the McAddams household for teaching Thingy to play with his thingy and trying to have sex with Cousin Nit, Lurch became a lowly Maytag repair man at a large shop. Follow me as we explore this FICTIONAL character as Lurch desperately tries to have an affair with one of his co-workers. Any resemblance to real life people is TOTALLY coincidental.
