This is the only time Kim loses her pants, instead of Ron.
She did not "lose" them in the same fashion as Ron routinely does. They were damaged, and is the first of two times.
When Kim buys her "emergency pants," the clerk allows her to wear the pants and sit on the counter so the label can be scanned. Most stores do not permit this practice because shoplifters tend to try on clothes and then wear them out of the store after removing the tags.
When Frugal checks to see how much cash people has sent him, he finds out that he has only $17.28, which means that someone has not even sent him a full dollar, assuming that he did not already have the 28 cents.
Smarty Mart gave Kim a $100 gift certificate for stopping Lucre.
Kim and Ron mock Frugal Lucre’s scheme because they don’t believe it matches up towards the other villains’ schemes. However, if the entire world did send Frugal Lucre the dollar he requested, he would have had roughly five and a half billion to six billion dollars, which is much more than Ron had in the episode Ron Millionaire, which is 99 million dollars - so shouldn't Kim have realized that his plan was better than most people thought it was? The episode Ron Millionaire has not appeared yet, it was a season 2 epsode.
Many families now have a computer, but some people, and even communities in the world are still without a computer. Take for example the town in Capt. Drakken episode, to name one, where if they have one, they hide it from Franklin Barkin. It is highly unlikely that every person on the planet could have sent Lucre a dollar, even if they were willing, but he would still have received a lot of money, which might have been around what Ron received in Ron Millionaire, but that is debatable.
When Kim and Ron arrive at Francis's door step, Kim's finger is ready to press the door bell in the middle of the door. But when they do a close up, her finger is in the side of the door, getting ready to press the door bell.
When Kim paid for the Club Banana pants, she pulled the money out of her pocket despite the fact that she was wearing the new pants, in which she wouldn’t have had money within them. Also, the huge shirt Kim was wearing because she needed new pants didn’t have any pockets, so it seems illogical that Kim could pull the money out of her pocket when she didn’t have any pockets to hold the money in the first place.
When Kim is uploading Frugal's file from the personnel manager's computer (upload in progress), the buttons on the front of the Kimmunicator are missing.
When Kim and Ron confront Lucre in his house, he traps them in a net. Yet when they first enter the basement, there is no net on the floor.
When Kim is in disguise to sneak into the personal manager's office, her hair is tied in a ponytail by a band. When she takes off her hat, her hair comes undone on its own, as if it was pulled through the hat's adjuster.
When Kim was looking at the pants, they are different colors, but when she starts running after Lucre, they're all one color.
When Kim and Ron enter the Smarty Mart where Francis works, there are no alarms by the doors, but when Kim snaps the alarm tag on his store vest, there are alarms at the store doors all of a sudden.
When Ron says 'Steel Toe versus Pain King!' his mouth doesn't move.
