Curling is particularly popular in Canada.
Improvements in ice making and changes in the rules to increase scoring and promote complex strategy have increased the already high popularity of the sport in Canada, and large television audiences watch annual curling telecasts, especially the Scotties Tournament of Hearts (the national championship for women), the Tim Hortons Brier (the national championship for men), and the women's and men's world championships.

With the 2010 Winter Olympics occurring in Vancouver, the writers wanted an Olympics-themed episode that could air during the Games.
The script was written by Rob LaZebnik—his fourth writing credit—, who originally considered having the plot revolve around Homer competing in four-man bobsled.
However, he decided a curling episode would allow for the plot to revolve around Homer and Marge and explore the issues of spouses competing together.
The writers used some artistic license, because although curling is an Olympic sport, mixed-doubles, which is featured in the episode, is not an Olympic event.
However, in the episode, it is explained that the event is being held as a demonstration sport.
Curling had previously been shown in the season 13 episode "The Bart Wants What It Wants", when the family visits Toronto.
In order to try to make the depiction of curling in the episode accurate, the writers visited a curling club and tried the sport themselves.
They also consulted with four-time American mixed curling champions Brady and Cristin Clark, as well as Rick Patzke, the chief operating officer of the United States Curling Association, who felt that the writers took a "genuine interest" in the sport.
On the issue of whether competitive curlers would be offended by the episode, LaZebnik said "When you hear "The Simpsons" is going to do their take on your sport, you naturally get a little alarmed, But we ended up being respectful I would say, even, surprisingly respectful.
Both Homer and Marge take it seriously."
Some curlers, including the Clarks and Patzke, felt that the exposure the sport received was beneficial.
Cristin Clark said "Although Homer Simpson probably isn't the ideal athlete I would want to see representing our sport, I just think it's great exposure."
Canadian curler Randy Ferbey, a four-time world champion, said "I'm sure they're going to somehow make a mockery of it like they do every other thing, but I think you need to take it with a grain of salt.
It brings attention to our sport and I think it's wonderful.
The more curling on TV, whether it's in an animated form or real form, the better.
"Sportscaster Bob Costas guest-starred in the episode as a caricature of himself.
