Before marrying Pam Dawber in 1986, Mark Harmon, the NCIS star, appeared on The Dating Game twice during college. In one instance, he chose a woman on the show but the relationship didn’t last. Harmon explained to Joan Rivers that despite the initial excitement, they mutually decided not to continue dating, citing a lack of common interests. Harmon also briefly dated Heather Locklear after a four-year relationship with Cristina Raines. However, his true love story began in 1986 when he met Pam Dawber through a mutual friend. They got married a year later and have remained happily married since. When asked about the secrets to a happy marriage, Harmon attributed it to luck and expressed gratitude for his wonderful wife.
