While Sam and Carly are holding up a poster, trying to advertise their web show behind a window on a talk show set, the letters on the poster go back and forth between smearing because of rain showers, and being perfectly fine.
When Carly and Sam have a banner that soon gets messed up, the Seattle Beat host says "next weekend..." in disgust when seeing the messed up banner. But when the same event is replayed in the web show, the host says: "be sure to..." in disgust instead of what she said before.
When Carly and Sam are watching Seattle Beat, Carly grabs the remote and turns off the TV. Then in the next shot, the TV is back on. Response: Actually, she mutes it, not turns it off. As in the next scene, you see the MUTE on the TV screen.
