I am not ashamed to admit, so here it goes. I absolutely love musicals. So I really found Mama-Mia eternally romantic and cute. Meryl Streep was amazing here, and to have the movie referenced here in a 30 Rock episode was just amazing.
Moving on, what we witnessed in this episode was truly the 30 Rock that made 30 Rock. Tracy acting all crazy, helping a 40 year old, who claims to be his son - though Tracy himself is 39 years old. Liz and Jenna take credit for the 'deal breaker' quote and get to pose on the cover page. But the main focus was Jack finding his real dad, after Liz stages a Mama-Mia situation where they call the 3 potential dads to NBC. It wasn't exactly hard for Jack to narrow down his choice, as one guy was Korean, and the other had no genitals. Steve Buscemi makes an appearance again. Now that's the deal-breaker.
