Don't let the bed bugs..getcha!

Last night when Shawn was taking Ethan to his bedroom he hollered out, "Don't let the bugs getcha!" (Instead of, "Don't let the bed bugs bite!")Then he said, "Don't let the lights burn out!" Well, that is a new one for me...anyone ever heard anything remotely close to that?! I have a feeling my son is taking after his mother. I am still being laughed at by my family -thanks to mom, dad, and Em- for my phrase, "In the middle of a hard rock!" (Supposed to be: "Between a rock and a hard place!")
