During an appearance on Tuesday morning's Today, the White Collar star partook in a TV-themed trivia challenge. But just as the games were beginning, Dennis Haskins, aka Mr. Belding, took the stage. Thiessen was clearly not impressed.
Just last month, Haskins told TMZ he's always supported a reunion.
"Honestly, the fans still love us and our show so much ... they deserve it!" he said.
Watch Thiessen's stunned reaction:
Are you still holding out for a Saved by the Bell reunion?
