Kurt (Brian Patrick Wade) and Penny had an on-again-off-again relationship for years on “The Big Bang Theory.” Despite his obvious physical qualities, however, it is difficult to decipher what she really saw in him. To begin with, he was a tyrant who took money and property from him. And if that wasn’t enough, he also liked to pick on people, with Leonard often being the victim of his bullying.
When Kurt was first introduced on the pilot episode of “The Big Bang Theory,” he and Penny had just gone through a dramatic breakup. As a result, she didn’t want to face him, so Sheldon and Leonard visited her to collect her belongings. Their mission failed, however, as Kurt used his imposing physique to intimidate the scientists into taking off their pants.
Kurt showed up again to attend Penny’s Halloween party later in Season 1, only to subject Leonard to more humiliation. Although this leads to Penny breaking up with the bully and falling into Leonard’s arms, it is further established that Kurt was bad news all along. It wasn’t the last chance she gave him either, as it was later revealed that he owed her $1800 and it took her a while to pay it back. Any redeemable qualities Penny saw in him behind closed doors were never revealed, so we can only assume he was downright terrible in every way.
