To be fair - this same exact thing could probably happen to me.
From COS:
TheVan Halenguitar god was attending Tool’s show in Los Angeles on Monday night with his son and bandmate, Wolf Van Halen. After the performance ended, an unknowing fan of Maynard James Keenan’s outfit asked the elder Van Halen to snap a pic of him standing in front of the stage. The guy had no idea to whom he’d just handed his phone, and that tickled Wolf something fierce.
“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,” Wolf Van Halen captioned a photo of the interaction onTwitter, “and that was my favorite moment from the @Tool show last night.”
