Elvin Tibideaux

&nbsp Elvin Tibideaux (Geoffrey Owens), is Sondra Huxtable's boyfriend, and later, husband. They met at Princeton University, where they both earned degrees. The two constantly bickered during early episodes, until his interactions with the Huxtables, particularly Clair, challenged him to confront his "male-chauvinist" attitudes.

When they return from their honeymoon, they shock Cliff and Clair by announcing their intentions to forego medical school and law school, and start a wilderness supply store in Brooklyn.

When his children are born, Elvin then announces that he will re-apply to medical school. This decision later convinces Sondra to resume her studies at law school.

Elvin was a wrestler in high school and for one year at Princeton University, but had to quit after injuring his hip. During the third season, he helped Theo with some strategy and moves.
