Yep. Two of them.

"The Voice" coach Blake Shelton jumped up out of his super-special "Voice" coach chair to join buddy Brad Paisley on stage for their song, "Don't Drink the Water," on Tuesday's final performance episode of the show's first season.

Paisley started the performance off solo, but after the first chorus, he was joined by Shelton... who had suddenly found a microphone hanging out by his chair.

Shelton hopped on stage where he happily sang his part and even played a little air guitar before critiquing Paisley's six-string skills.

The song, from Paisley's latest record, was Shelton's second performance of the evening. Earlier, he took the stage to perform with his team member Dia Frampton. They sang Tom Petty's "Won't Back Down" to rave reviews.
