For Sheldon to be a Taurus he must have been born between April 20 and Might 20, which true followers will know can’t be the case.
It appears even showrunners might have noticed the plot error, as later in season eight Penny appropriately refers to Sheldon as a Pisces.
Nonetheless, the continuity error didn’t go a miss from die onerous followers of the present, with one person taking the matter to Reddit.
One person posted: “Wait, how the hell can Sheldon be both a Taurus and a Pisces? Penny switches between the two halfway through the show.”
