Mars needs retards

For months, I've been seeing this commercial for Mars bars. (You know, the one that goes, "Are you Cousin Bill-y?" Do you want me to be? [nods] Well, ah shore am!") Actually, it's not quite true that I've been seeing it. I've been catching bits of it out of the corner of my eye and kind of listening to it while I wait for the commercial break to end.

Just now, I finally clued into the fact that the slogan that I've been hearing at the end is "Recharge on Mars". All this time, I've been hearing it as "Retards on Mars".
