I don't have to explain what Sports Illustrated Swimsuit: 50 Years of Beautiful (8 p.m., NBC/Ch. 5) is. The title says it all.
What's interesting is that just a few years ago, KSL refused to air a Sports Illustrated swimsuit special. Because it was too risque.
What, exactly, has changed since KSL refused to air that other Sports Illustrated swimsuit special I have no idea. But, clearly, things can change at Channel 5.
Elsewhere on TV ...
How I Met Your Mother (7 p.m., CBS/Ch. 2): A drunken Barney goes missing on his wedding day.
The Bachelor (7 p.m., ABC/Ch. 4): The bachelor and the women travel to Vietnam.<
