Continuity mistake: If you check the Post-it note on the previous episode and this one's, it is not the same note. It's very similar, but the "t" in "Can't" is different, the apostrophe in "I'm" is within the word then above it, and other small differences.

Continuity mistake: In this episode, Brady has the Chicken Pox. But when Robert visits Miranda at home and picks up Brady, there is absolutely no sign at all that he has Chicken Pox. It takes awhile to get over Chicken Pox, and for them to fade. So even if Brady is recovering from having Chicken Pox recently, he would still show signs of it. It couldn't go away that fast, and it's way too soon for Brady to be completely clear. (00:12:55)
Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
