'Downright scared!' Watch Al and Matt's 'Sharknado 2' cameo

A storm is coming to Manhattan straight out of Al Roker's nightmares — an EF-5 sharknado. 

"I'm really nervous about this,'' Al says. "In fact, I'm downright scared." 

On Tuesday, Syfy released a sneak peek of the surefire Emmy-winning performance of Al and Matt Lauer in the movie event that promises to "break Twitter" in the words of star Ian Ziering. The TODAY duo have a cameo in "Sharknado 2: The Second One," the sequel to the social media phenomenon of the first "Sharknado" involving Ziering, a chainsaw, and (of course) flying sharks in tornadoes. Ziering is back as Fin Shepard for the newest Sharknado, which premieres Wednesday at 9 p.m. ET on Syfy, but on Tuesday it was all about Matt and Al.
