Sean then hands Peter a piece of paper with a phone number on it, and Peter calls the operator. The number Peter gives the operator is the same number Felicia has called her grandmother collect with - in Texas - several times - not Frisco's apt. in New York, where Felicia is staying.

However, when there is an establishing shot of the restaurant, it states in the window that there is something for $9.99.
Yomigaere! Eiyuu Densetsu - S1-E1
Character mistake: Not to dispute physics in an anime about people drawing arcane cosmic powers from constellations, but when Marin explains to Seiya what happens when you shatter a rock into smaller pebbles, she says that you "destroy its atoms." That's not how physics works and luckily for her, Seiya and everyone else in Greece at the time, she did not create a nuclear fission in the palm of her hand just to prove her point.

Character mistake: The store window's sign says, "Denver Mercatile" rather than "Mercantile."
Character mistake: When Geoffrey serves tea after his sassy cough at Vivian's sentence about High Tea not being a sacred institution, the actor messes up when it's time to actually serve tea, with a napkin getting caught in the teacup saucer. Granted, accidents do happen, but it's quite uncharacteristic for the perfect butler Geoffrey is portrayed to be, and simply a flub by Joseph Marcell. (00:17:45)
Character mistake: Sasha refers to the 'murder' on Thursday 4th June 1982. The date in question was on a Friday.
Character mistake: When John-Boy reads the nursery rhyme "Simple Simon" to his nephew, John-Boy points to the colorful illustrations in this book and tells John Curtis, "See, that's Simple Simon, he's a bear."

Character mistake: In the epilogue, Charlie illustrates the relationship of mathematics to real life by discussing the golden ratio and its presence in a host of real-life situations, including the shape of a nautilus shell and the distribution of petals in a flower. These claims are disputed by some mathematicians (see http://en.wikipedia.org/wiki/Golden_ratio#Nature), and the one about the nautilus shell one is untrue (see http://en.wikipedia.org/wiki/Golden_spiral#Spirals_in_nature). It's possible Charlie is just repeating what he has read or heard without investigating it for himself, but this is uncharacteristic of him.
Character mistake: Edith says in a story that Archie has a brother Phil. In actuality Archie had 1 brother, Fred.
The Dark and Bloody Ground - S1-E3

Character mistake: In one episode, John, Meldrick and Tim are called down to their bank because they're getting a business loan to buy the Waterfront Bar (the bank's policy is to give good news in person). They start arguing and Tim announces at one point that "I've got a platinum card, Frank", which is marvelous, except he's talking to Meldrick.
Character mistake: Dr. Sloan and Quinn are in the victim's apartment. Right before Dr. Sloan opens the door for the old lady witness to ID Quinn, Dr. Sloan says, "saw a man visiting Holly the night before he died." Holly is a woman. Dr. Sloan should have said "she." (00:33:51)
Character mistake: It's more than unlikely that a prison guard would leave a suspected murderer (George) alone with anyone, especially a woman (Edna) for minutes. (00:24:28)
Character mistake: After Anakin says to use the walkers (AT-TEs) as boarding vessels, Rex calls the first one an AT-AT (a vehicle that does not even exist at this point in-universe) while ordering a battalion of clones into it. (00:04:10)
