David Clemmons has taught at Keller High for 13 years. He won Wednesday night’s game making him a semi-finalist on the nationally televised game show.

Dozens of students and staff members packed into the schools lunch room Wednesday night for a watch party.

“He supports us so much in his life and I just really wanted to pay that back to him,” said Junior Grace Farley.

Clemmons said competing on the show is something he has tried to do for more than 30 years after he saw his first episode back in 1984.

“It’s been a 33 year dream to be on Jeopardy so it was very exciting,” he said.

Clemmons now advances to the semi-finals round, which was already recorded but he is not allowed to comment on due to a nondisclosure contract that he signed.
