This is the first time Wonder Woman appears in public as Diana Prince without her glasses as a disguise.
When Diana disclaims her tennis skills, she refers to Tracy Austin, then a 16-year-old prodigy, and Chris Evert, then the #1 player in the world.
The title may be a nod to the 1967 Tony-nominated musical, "I Do! I Do!" - about the ups and downs of a married couple, spanning 50 years.
Diana does not use her bracelets to deflect against her enemies in this episode.
