S4·E28 Mountain Man

Lex Buckman, a mountain man - huge, dirty, and unshaven - gives the men in Laramie a lot to talk about-and admire- by his shows of strength and prowess. However, once he sees Lily, he tells her he needs a wife and ""You're it!"". Nothing she can say can dissuade him, until she wheedles Dan into telling him they're engaged. Instead of running Lex off, he decides to eliminate the competition. Lily and Johnny spend the rest of the show trying to protect Dan from Lex, some with comic results.
