Big Bang Theory plot hole: Key Howard and Bernadette scene opens up major mistake

In episode seven, The Dumpling Paradox, viewers were treated to a full view of Howard Wolowitz’s hairy chest. 

Despite a full display of the engineer’s unwaxed physique appearing in season one, this causes a major continuity issue once Howard begins dating his new girlfriend Bernadette (Melissa Rauch). 

One observant fan took to Reddit to outline some of The Big Bang Theory’s most egregious plot misdemeanours. 

Redditor cornerboyfrank8 posted: “In season four episode eight, Bernadette says that Howard has only one chest hair.”
