Raj and Penny's father were on Star Trek

The show made a lot of jokes of Star Trek Original and Star Trek The Next Generation, almost ignoring the rest of the franchise. So, if I could change anything on the show, I would add more jokes about the entire universe of ST, specially with the fact that Raj's father was present in 2 different series - Deep Space 9 and Voyager, where he was the father of one if the main characters in DS9. In other hand, Penny's father was present in Enterprise and almost become the 1st captain ever. Imagine the possibility of jokes that were possibly here.
