I know the pregnancy test in the trash has been done but seriously if you look at just about anything on the show (and others) it's all been done before. And Hollywood likes what (it thinks) works. Maybe they can update it and have Leonard over at Penny having a date, she's in the bathroom when her phone beep, it's a message from her doctor or something, maybe a phone app that keeps track of her cycle. And she's late, plus has been sick in the mornings. Of course she's not pregnant but Leonard thinks she is, and he proposes?
Visually the test in the trash is easy to set up but I'm sure they could use the idea and update it.
BTW just watched
The Boyfriend Complexity and now more then every I want to see Penny's dad again and meet her mom.
ETA - speaking of action figures I was hoping the guys would get there hands on the
Steve Jobs one, but it's been pulled from sale, maybe the guys track down one and fight over it
