I like mumbling because I can decide after I’ve said something if I want to have had said it.

Me: [mumbles] That’s probably because you waste so much time watching TV.

Her: What did you say?

Me: Contemplates wisdom of having said that

Me: Huh? Nothing. Don’t worry about it.

Her: Nikhil, what the hell did you just say to me?

Me: Never mind!

Her: Sounds like you had something to say!

Me: Well, I retract it!
