When is Thursday the 19th??

I am so sick of changing diapers! I feel like I change diapers all day and all night. We have experimented with potty training for Peyton but he didn't seem like he was ready. Everytime I change his poopy diapers I ask him "when are you going to go poop on the potty" and everytime his reply is "at Thursday 19". This has become his answer to every "when" question. We have asked him "when do you want to go to the park?" "when are you going to feed yourself?" "when is your football, basketball, or soccer game?" "when are you going to go golfing with Dad?" "when are we going to see Mickey?" the list goes on and on. His reply is ALWAYS "at Thursday 19." I don't know when Thursday the 19th is, but a lot will be happening that day and it will be a glorious day!!
