Ferguson was riffing on how he no longer has the attention span to read even tweets when Lennon said, "That's really the only place I get my news, is from your tweets."
Saying that was really sad, Ferguson upped the ante by claiming that he gets all his news from commercials.
As if by magic, a commercial break was just coming up on the show, so just like a "real" talk show the band started to play into the break.
However, this being the "Late Late Show," the band was comprised of Ferguson and Lennon playing air instruments and making all the musical noises themselves.
