Country stars know how to have fun on tour ... especially at the expense of each other! From on-stage invaders to unexpected video swaps, artists have pulled off some pretty funny pranks when on the road together.

Brad Paisley loves a good prank, so of course he's featured in the above video -- twice, actually. But you'll also see Tim McGraw playing a simple-but-effective joke on Lady Antebellum and Martina McBride shaking what her mama gave (or didn't give) her at Trace Adkins' expense. There's also plenty of chickens and goats -- this is country music, after all!

Press play on the video above to see six of the best country music tour pranks.
