The Big Bang Theory Quiz: You'll Never 100% This Howard And Raj Fill In The Gaps Quiz

Howard and Raj, what a couple. Sure, The Big Bang Theory is mainly centred around the will-they-won't-they relationship of Leonard and Penny and, in the latter seasons, the relationship between Sheldon and Amy, but the real dynamic couple are Mr. Howard Wolowitz and Dr. Raj Koothrappali.

In the beginning of the show, Raj and Howard were two young singles trying desperately (and admittedly rather creepily) to gain the affections of the opposite gender. Unsurprisingly, Howard's overly forward approach to women and Raj's selective mutism resulted in the two of them going home alone with only each other for comfort. Despite the two of them getting into relationships of their own throughout the show, their geeky friendship never wavered and was a consistent source of laughter throughout the 12 seasons.

If you are indeed a fan of the lovable losers, Howard an Raj, then this quiz is certainly for you! The questions that will come up will stretch your memory on how well you think you know some of their most hilarious and memorable quotes from The Big Bang Theory. From horny engineering to inventions aimed at killing Sheldon, see if you can fill in the gaps of this Howard and Raj quiz.
