Creator Backlash - Most of the members have expressed their dislike for quite a few of their songs and concepts:
Taeyeon said she hates all their title songs except for "Run, Devil, Run" and "Mr. Mr."
Sooyoung said she dislikes cute concepts, like "Gee" and "Oh!", and wishes to perform more serious songs. She even hated the group's name when she first heard it because she was hoping for a less cutesy name.
Seohyun said she hated the cringe-worthy lyrics of "Oh!"
Tiffany was ridiculed by her family and friends in the United States for dancing with lollipops in "Kissing You", causing her to loathe the song. She recently revealed the SNSD songs she liked are rare.
Hyoyeon almost left the group because she couldn't adapt to the cutesy dancing SNSD was initially known for. She had trained her entire life for more serious forms of dancing.
Yuri was embarrassed by their choreography from post-"Into The New World" to pre-"Genie".
Jessica wasn't a fan of the song "Ooh La La" from their debut album for its lyrics and dance.
Development Hell - The full music video for Beep Beep was supposedly going to be released in late May 2013. They released it in early December 2013 instead.
Easter Egg - In "I Got A Boy" when Jessica says "Don't stop, let's bring it back to 140", she means it. The song does go back to 140, not only in bpmnote beats per minute, but it also goes back to the 1:40 segment in the song itself.
S♥nesnote From "소원" (sowon), which means "wish", but also references how SNSD and their fans are one.

Tiffany. She was a big fan of Kim Hyun Joong (the leader) of SS501 back when she was still a trainee (check out her pre-debut Q&A here). On an episode of the now-defuct Korean TV show Star Golden Bell, SNSD got to guest-star with the members of SS 501 themselves. And when the host conducted a survey in which the members of SS 501 picked the most popular / their favorite SNSD member, they picked Tiffany. (That includes Mr. Kim Hyun Joong). After that, Kim Hyun Joong stated that he looks up Tiffany on the internet. Fangirling from her side most likely ensued.
Sunny also had a fangirl moment when her idol Lee Bumsoo (a famous Korean actor) became SNSD's acting teacher on Horror Movie Factory.
In MTV Lifestyle, we have Seohyun's own fangirl moment when she visited the Keroro dubbing studio. She even got to dub Keroro's voice!
Scully Box - The girls range in height from 155 cm (Sunny) to 170 cm (Sooyoung). While there's not much they can do about the massive differences whilst performing (aside from the shoes they wear, but that was mostly done during their debut days), photoshoots are another matter, and often result in the employment of these.
During their time as trainees in SM, their group's name was "YeoDan Team".note From 여자 단체(Yeoja Danche) which means "Female Group" - "Yeoja Danche team" literally translates to "Female Group Team" The name "Super Girls" was preferred by the press and the netizens.
Jessica was originally considered for a SNSD subunit, along with Tiffany and Seohyun, they even recorded a song together, “Oppa Nappa”. This is known within Sones, the three were often even promoted together but in the end she was replaced with Taeyeon and Tae Ti Seo was born. What happened during this time is a mystery, and many think that this was what torpedoed the Taeng Sic ship.
"Catch Me If You Can" had to be re-recorded and re-shot when Jessica left the group. It wasn't clear that it was originally for 9 members song until Jessica was caught singing a line in her reality show prior to its release and screenshots of the MV were leaked, along with a draft of the MV itself.
