On The Big Bang Theory episode ‘The Holiday Summation,’ Leonard (Johnny Galecki) and Penny (Kaley Cuoco) are having the gang over for a post New Year’s get together. Leonard makes sure that all the Christmas decorations are removed knowing how Sheldon (Jim Parsons) feels about them after New Year’s Day. While putting the food out for the party, Bernadette texts Penny to say they’re running late due to the baby throwing up on Howard and Howard throwing up on the baby.
A scene shows Bernadette at home in sweats having a really bad hair day after a long night with the baby. Penny on the other hand is rocking her familiar long locks. Compared to the last time we saw Penny (in December 2016), she’s glamming up her hair game in 2017. We hope it’s a trend. The Big Bang Theory airs Thursdays at 8pm on CBS.
