At AdWeek, "Bar Refaeli Swaps Spit With Jesse Heiman in Go Daddy Super Bowl Ad":
The couple did 45 takes of the kiss, Go Daddy claimed, adding that [Jesse] Heiman afterward said he felt like he won the "championship of men."More at that link.
Likewise, this is Refaeli's first Super Bowl commercial. She probably had never kissed a homely character actor before, either.
Yeah, that Heiman dude's a lucky man. One really lucky dude.
