I did a tape for a kid saying, ”Hey buddy, it’’s Michael Knight, Michael Knight, come on, wake up, wake up, wake up”.”The phone rang and they said, ”Remember that kid you did the tape for that was hit at that crosswalk in London? Well we played the tape for him and he came out of the coma,”” said Hasselhoff.The actor, who later met the child, claims that such miracles have happened to him many times.”I went, ”Whoa, whoa”.
