The Aussies of 5 Seconds of Summer are always down for a good prank.

5 Seconds of Summer's Ashton Irwin Gave His Bandmate Calum Hood Solid Advice That 'Really Hit' The Bassist

On Thursday, the band uploaded a video to their official YouTube Channel of themselves dressed up as grandparents and hitting up a Target to buy their live album, LIVESOS.

The band previously did a Target prank back in July, but they were Target employees attempting to get customers to buy their debut self-titled album. Hilarity ensues in both videos.

5 Seconds of Summer 'Dressed Up' Like Grandparents

The band was super excited to share their second Target prank with their fans. On Facebook they said, "So we went back to Target..."

At first in the new Target prank video, the guys are seen getting dressed up as elderly people. Typical 5SOS humor ensues moments later as they break out into song, the Family Guy theme song, and dance.

Then, Ashton Irwin, who is dressed like a grandpa, introduces bandmate Luke Hemmings as his "sexy wife Melissa" while Michael Clifford introduces himself as Moira and Calum Hood as "my brother." Hood stated his name is Kenny.

The real entertainment begins once they're inside the Target. At one point "Melissa" throws herself down on the floor. Another highlight is "Moira" slapping "Melissa" as "Kenny" looks at the display of LIVESOS albums while Irwin's elderly alter ego tries to stop the violence.

The band even breaks out into dancing in the aisles of Target.

Irwin cracks the joke at the end of the video after their elderly selves bought LIVESOS that they're "5 Seconds of Retirement."

Basically elderly 5SOS is just as amusing as Target employees 5SOS.

5SOS fans, which Target prank do you like more?
