Taylor taught him to play the Foster The People megahit “Pumped Up Kicks” and even improvised the lyrics a little for humor’s sake, to play up Ellen’s curiosity on their dating situation. It (roughly) goes:
Efron: “Ellen works a long day, giving weird interviews in a slick cool sweater and it gets kind of weird getting called out like we’re boyfriend and girlfriend…”
Chorus: “Every single time I come on this show it’s really weird really weird, all because of Ellen, every single time I come on this show it’s really weird, really weird.
“She always asked me who I’m dating every time I’m on this show and I don’t even know why, but it gets five million hits on YouTube.”
