The Platonic Permutation - S9-E9

Continuity mistake: In episode 16 of season 1, Penny is talking about making a cake for Leonard's birthday and states she knows his birthday because she was checking a horoscope for him. But in this episode she does not know when his birthday is, which leads to Leonard revealing he was secretly reading Penny's diary. (00:40:00)

This is perhaps true for two people who rarely have contact, but I would list this as a character mistake. Penny and Leonard are in a serious relationship and are married at this point.

This is also a couple who BOTH forgot it was their anniversary.

I forgot my wife's birthday on a number of occasions. It's one of the reasons she is now my ex-wife.

There's a difference between forgetting and not knowing.

I've been married for seven years and my husband still doesn't know my birthday. It's the 24th but sometimes he thinks it's the 24th or the 4th or the 20th etc. And especially since Leonard doesn't celebrate his birthday, it's not something that's going to remain in the forefront of Penny's mind.
