Is this excellent or exceptionally petty? Seeing as how Sum 41‘s (former?) frontman and owner of many unnecessary consonants Deryck Whibley is supposedly still close with his ex-wife Avril Lavigne, we’re leaning toward excellent. Above is Whibley’s Halloween costume in which he’s dressed as his mopey ex in her “Complicated” heyday, while his girlfriend threw on a horrible wig and cheesy t-shirt to become Lavigne’s husband, Chad Kroeger of Nickleback AKA what happens if you cross Aslan the Lion with a vodka Red Bull.

Also nudging this into the field of excellence is Nickelback’s bitter response: Hey Deryck loved the costumes! we were going to dress up as you guys this year but all the parties had celebrity themes haha! -CK

Chemical burns all around?
