Mom? Is that you?

My MOTHER pointed out the perverted part of this jingle:

Sleepy's the mattress proffesionals, doing it right,
Trust Sleepy's for the Rest. Of. Your. Life.

My MOTHER said:
"doing it right......hmmm..... doesn't that sound like people having s**?"

My reaction: WOW!! Mom! Are you okay?????? Since when are you perverted?
