Back when Jennifer Garner was researching a role of a dolphin who turns into a girl on 'Fantasy Island,' she made a too-close connection with a dolphin.
"I had my feet dangling in the water," she told David Letterman Tuesday night. "And the dolphin came and swam right over my foot. I thought, 'That was so cool!'"
The dolphin started swimming around her leg faster and faster until something happened.
"I said to the trainer, 'I think the dolphin just peed,'" she said. "He said, 'No, ma'am, no.'"
Jennifer is promoting 'Valentine's Day,' a movie about a more conventional type of love, out Friday.WATCH:
