Speaking to 13,000 Microsoft employees, Ballmer took the stage at Seattle's KeyArena and jumped around to a variety of songs, as he tends to do.
Among the background tunes were "Can't Hold Us" by Macklemore and Ryan Lewis, "Wanna Be Startin' Something" by Michael Jackson -- a track the company played at its first employee meeting in 1983 -- and then Bill Medley and Jennifer Warnes' "I've Had the Time of My Life," during which he screamed that he'd had the time of his life with the company.
In case you aren't aware of how crazy Ballmer can get, check out the video at the top of this post.
Earlier this year, Microsoft announced that Ballmer would be retiring within 12 months, so this is the last time the long-running executive will address his troops. Understandably, there was a lot of emotion.
"We have unbelievable potential in front of us, we have an unbelievable destiny," Ballmer said, according to Reuters. "Only our company and a handful of others are poised to write the future."
With tears running down his face, Ballmer paused to enjoy the moment.
"You work for the greatest company in the world, soak it in," he said, according to the Verge.
