We're sure you've all seen this photo of the cast of the Big Bang Theory dressed up in The Rocky Horror Picture Show costumes that was published a few years ago.
What many people don't realise is not only were the cast all big fans of the movie, but so were a lot of the production crew on the Big Bang Theory, in fact there were rumours of regular screenings each year after the season wrap up parties.
We have an American friend who married one of the crew who worked on the show and she's been over for a visit recently and that told us about the "Easter Egg" hidden on those super fast Big Bang Theory titles that links the show to The Rocky Horror Picture Show.
Can you spot the Easter Egg?

Did you see it?
This was the best we could get it from the screenshots, but you can clearly see they have used the chemical formula/DNA? writing that is on the wall in Frank's lab and added it to the medical shot from the 1970's section of the titles.
Yet another weird Rocky Horror link for the archives!
