Jeopardy! host Ken Jennings has ruled out growing a mustache like his predecessor, Alex Trebek. Jennings joked that the ratings would drop if he tried to emulate Trebek’s iconic facial hair. Despite his self-deprecating humor, many fans would likely tune in to see Jennings pay tribute to Trebek in such a way. Trebek’s mustache was a signature part of his look for many years, but he eventually shaved it off in 2001. He grew it back in 2014, but viewers voted for him to shave it off again. In 2018, the mustache returned, along with a beard, and fans were obsessed. Trebek’s beard made another appearance in a video update during the pandemic in 2020.
