The traffic summons that Sheldon receives shows that he was photographed on November 16th driving Penny to hospital. The episode in which this happens, The Adhesive Duck Deficiency, was indeed first aired on November 16th, 2009.
Sheldon misses out on meeting Stan Lee at a comic book signing because he must appear in traffic court. The nameplate on his bench shows the judge's name is Judge J. Kirby. Jack Kirby was a comic book artist who often worked alongside Stan Lee and helped create some of Marvel Comics most popular titles.
Sheldon tells Penny, "The moving finger writes, and having writ, moves on". This is a quotation from verse 51 of the Rubáiyát of Omar Khayyám, a collection of poems originally written around the 11th century AD, as translated from Persian into English by Edward FitzGerald (first published in 1859).
When Sheldon and Penny go over to Stan Lee's house at the end of the episode, Stan Lee states sarcastically, "you fanboys are unbelievable. Why don't you just come in and watch the Lakers game." Sheldon claims that he is not much of a sports fan but okay." However in several episodes Sheldon has stated that his father forced him to watch football and is an expert at that sport. Sheldon however is not a sportsfan, only an expert in the rules.
