The appearance will mark Thicke’s fourth time making a cameo in a Robin Sparkles-centric episode, and this will be Van Der Beek’s second time on the show. In past episodes, Thicke has played himself while Beek portrayed Simon, Robin’s first boyfriend who also appeared in her “Sandcastles in the Sand” music video. Trebek has also previously appeared on the show.

How I Met Your Mother, which recently was rumored to be returning for a ninth season, returns with new episodes Jan. 14.
