'Two And A Half Men': Walden, Alan And Lyndsey Makes The Most Awkward Threesome Ever (VIDEO)

"Two and a Half Men" almost went into uncharted territory after Alan proposed the idea of spicing up their love life. After quickly rejecting some ideas inspired by "Fifty Shades of Grey," Lyndsey pushed Alan to present some of his own personal fantasies, and then she jumped on the idea of a threesome.

The only problem for Alan was that she suggested that before they go through with his idea of a threesome, he needed to participate in her threesome ... with Walden. Knowing he was outclassed in almost every way physically by Walden, Alan was reluctant, but he approached Walden. To Alan's surprise, Walden was game.

Or at least he thought he was. Once they were in the moment, it became pretty clear that Lyndsey only had eyes for Walden, leaving Alan to awkwardly pet and then lick her back. But Walden only had eyes for Zoey, and broke down. He simply wasn't ready.

That didn't last long, though. When Alan and Lyndsey brought back a woman to fulfill Alan's threesome fantasy, she was intercepted by Walden and wound up in bed with him. Not a successful series of threesomes by any means.
