Sasson Jeans

Everyone in New York was ooh-ing and ahh-ing about the New York Rangers in 1979, and it wasn't just because of their unlikely run to the Stanley Cup Final.

That's because the Rangers, specifically Ron Duguay, Dave Maloney, Anders Hedberg and Hockey Hall of Famer Phil Esposito, were wowing fans in a commercial for Sasson Jeans.

The four Rangers show off remarkable flexibility as they glide across the ice, singing "Ooh, la la, Sasson" in their Sasson Jeans.
Lest you think this was a one-off of awesomeness, the Rangers even returned for a sequel, with Ron Greschner replacing Duguay, wowing some female fans in 1980.
