Of course, the Academy Awards won't be presented until Sunday, but MacFarlane won laughs from the show's director during a rehearsal Thursday night inside the Dolby Theatre.

The 39-year-old entertainer wore jeans and sneakers as he practiced the various introductions he'll make during show night.

"Excellent. Looks really, really good, Seth," director Don Mischer's voice boomed over a loudspeaker onstage. "You're getting lots of laughs in the control room."

Sandra Bullock got a few laughs of her own at the Dolby Theatre Thursday. The actress breezed through the theater for a quick rehearsal wearing sky-high heels with cropped pants and pin-straight hair, a credential hanging from her neck. She chewed gum, chatted with MacFarlane and left the show's producers cracking up.

Aside from hosting the event, MacFarlane is also expected to perform a special musical number alongside singer and actress Kristin Chenoweth at the close of the prestigious awards show ceremony.
