An even bigger one: "I always thought I'd be a singer." Hi there, Queen of Country...
Yet another example:
Jake: Wouldn't it be cool to be on TV?
Reba: Nah. I think it would be cool to be a singer.
Yet another, when Reba is planning Van and Cheyenne's vow renewals, Cheyenne comments how she's making everything so fancy. Reba turns and say, "Well, Fancy is my name." "Fancy" was one of Reba McEntire's most popular (and some would say signature) song.
Reba's statement towards the minor character played by Kelly Clarkson: "If she goes on TV, America's going to love her." Just about anyone who knows how the first season of American Idol ended would understand the humor from that sentence.
I Want You to Meet an Old Friend of Mine: By the time Kelly Clarkson guest-starred on the show, she had already forged a great friendship with Mc Entire, as the former had requested to sing with the latter on the American Idol Season 1 finale, and following Clarkson's win on that show, the two toured/sang together frequently. Also becomes a retroactive case of Real-Life Relative, as Clarkson would go on to marry Reba's son-in-law in 2013.
Reality Subtext: Melissa Peterman's weight loss and Scarlett Pomers' eating disorder are both written into the script.
Reba was the highest rated show on the WB, but when it merged with UPN to form CW, they were going for a different demographic, and it wasn't sure if the show would make it through the merge. Due to financial penalties (see Un-Cancelled below), The CW ordered 13 episodes for a sixth season.
Despite a promising performance in its sixth season (the show was the highest rated sitcom on the new network and increased the ratings from the shows previously slotted there), the show was cancelled since it was felt that it didn't hit the right demographics.
And such moves seemed to have not gone unnoticed, if the following exchange was of any indication:
Van: If you take away loyalty and ethics from business, do you know what you got?
Un-Canceled: The show was effectively (though not officially) cancelled after its 5th season upon the merger of UPN and The WB into The CW. However, finances saved the show - The WB had renewed the show for two seasons the previous year, and the new network would be on the hook to the producers if a sixth season was not ordered.
