In the scene when Shawn is rushing around making sure everyone is doing their part to impress the Ganders from Stanford, his mother says she needs a drink from the icebox. Shawn tells her OK, and then he goes downstairs with Ashley at the refrigerator, but never gets the champagne. When Shawn goes back up to check on if his mom is dressed, she has the glass of champagne that no one went to get! Also when Shawn tells Lance to stay in his room, he tells Lance "some very important people are coming" even though they've already rung the doorbell. Shouldn't he have said "some very important people are here".
