On Wednesday night’s Anderson Cooper 360, Cooper featured Billy Corgan in his recurring RidicuList segment for appearing on the cover of PAWS Chicago magazine — something that happened more than five months ago, mind you — and went on to ridicule the wrestling-themed furniture commercial Corgan appeared in last year (apparently he didn’t hear about the eight-hour Siddhartha performance?) before lamenting that watching his alt-rock heroes age is reminding him of his own mortality. Here’s the segment:

Where are they now? From 6 million-selling album to posing with cats. The #RidicuList: http://t.co/hd4rRMV64H @CNN pic.twitter.com/7ULRsyWCsm

Presumably this untimely takedown was brought on by some in-studio chatter about Halloween, which led to a discussion of pumpkins, which inspired some CNN staffer to ask if his or her coworkers had seen Corgan’s PAWS cover. Or maybe Cooper has just been looking for a chance to flaunt his insightful music commentary with offhand remarks such as this “Cherub Rock” critique: “Alright, so maybe the guitar sound is a bit derivative of My Bloody Valentine, but that’s beside the point.” Whatever the reason Cooper decided to make fun of Corgan, Corgan didn’t take well to it. As Loudwire notes, he tweeted a curt response last night:

@andersoncooper Sorry to disappoint, but when I'm not raising cain for a great organization like @PAWSchicago, I'm still making REAL music
