Usually when a television series goes on for four seasons or more, they begin to lose their way and seem to forget what made them so great in the first place. However, it seems that the guys over at The Big Bang Theory know something that most people don't.
The Big Bang Theory is approaching its seventh season and, while the show might not quite be as good as it was when it was at its best, it is still pretty darn good and one of the best comedy series on television at the moment. One thing The Big Bang Theory does manage to do, is give us some impressive guest stars.
In the past, we have had the likes of Summer Glau, Stephen Hawking, George Takei, Buzz Aldrin and Stan Lee, to name just a few. So, with The Big Bang Theory season seven just around the corner, which impressive guest stars can we expect to see this time around.
Well, Melissa Rauch, who plays the role of Bernadette in The Big Bang Theory, admits that they will struggle to get anyone that can beat the guest stars they have had in the past. She claimed, "It's hard to top the ones we've had," which is a very fair point.
With The Big Bang Theory season seven premiere airing on CBS on September 26, we do not have too much longer to wait to find out.
