It's hard to remember a time when Taylor Swift toured as an opening act, but it was less than 10 years ago that the superstar opened for Keith Urban on select dates of his 2009 Escape Together World Tour.

Swift may have taken the stage first, but the "... Ready for It?" singer got the last laugh at a Kansas City, Mo., stop when she and her band members upstaged the Aussie headliner by dressing as the iconic band KISS during Urban's "Kiss a Girl" performance.

Urban seemed genuinely shocked by his unexpected visitors, even though onstage pranks have become a somewhat expected tradition on the country music touring circuit. He took the prank in stride, not even missing a beat despite being surrounded by a group of sharp-dressed practical jokers (and a few dancing Hershey kisses for good measure).

These days, Swift has gone pop and is headlining her own sold out stadium tours.
