When Bernadette and Howard are in the kitchen talking about having reservations about each other, Howard mentions he never did. This is false. The first time, he waited over a week to call Bernadette back because he wasn't sure she was right for him. The second time, he was at a bar at the Cheesecake Factory with Sheldon, hesitating because he didn't want to sign a prenup.
Sheldon mentions he has a 4:30 reservation at Applebee's for Meemaw, Amy, and himself. When he says this at his apartment, it is shown to be nighttime outside the window. It would have to be daylight in order for Sheldon's statement to be accurate.
Applebee's doesn't take reservations.
When Amy first meets Meemaw, they shake hands as if they have never met and have no prior history. However, in The Clean Room Infiltration (2014), Amy gives Sheldon Christmas cookies that she baked after she called Meemaw and got the recipe. Obviously, they've spoken and know who each other are.
That is not true: Amy might have obtained the recipe in other ways, such as asking it to Sheldon's mother, or having Leonard ask it to Meemaw.

Stage lights can be seen in the reflection of Meemaw's glasses.
