That's Rock 'n' Roll Puns

So my 1st Born came into this world on Monday night and we were discharged on Thursday. Upon leaving our room, we were given a metal cart to place our belongings on including our son (in his car seat). As we made our way to the garage, I noticed that when the cart was rolling his car seat would rock a bit. I took this opportunity to exclaim “hey (son’s name) you’re really rockin’ ‘n’ rollin’ now.” My wife then truly realized what is in store for her.
