Eddie Van Halen arrives for the George Lopez Foundation 10th Anniversary Celebration Party at Baltaire on April 30, 2017 in Los Angeles. 

Eddie Van Halen attended a Los Angeles Tool concert on Monday night (Oct. 21) with his son Wolfgang, and the two had a hilarious interaction with an unknowing fan. 

Wolf took to social media to share a photo of his Rock & Roll Hall of Famer father taking a picture of the fan, who did not recognize the rocker. "A guy asked my dad if he could take a picture of him with the stage behind him, having no idea who he just asked, and that was my favorite moment from the @Tool  show last night," he wrote in the caption.

Check it out below. Still waiting on the fan to share his facepalm moment.
