This made me laugh so hard. During Adam Lambert and Allison Iraheta's "Slow Ride" duet in Newark last night, fans threw bras and other assorted things on stage. While I think all the throwing of stuff on stage is getting ridiculous, the way Adam reacted to it was hysterical. After Allison stepped on a pink tassel-looking thing (and thankfully didn't slip on it), she picked it up, twirled it around and handed it to Adam. While singing, he held it up, looked at it, and added a new lyric to the song - "What the f___ is this?!" - before throwing it back into the audience.
He didn't actually say the word - just the first consonant, so no need for a warning label. The antics start around the 1:18 mark.
