Okay in being a super Clueless fan I can't believe it took me so long to spot this mistake...

In the scene after Cher fails her driving test, when she and Ty are sitting near the fire place Ty mentions she wants to get rid of the things she kept that reminded her of Elton. Here's the slip up, Ty tells Cher that she kept the towel Elton ran and got for her at the Valley party, when she got knocked on the head. Elton never ran and got her a towel. Go to that scene, he did pick her up and put her on the table, but Cher was the one that got the towel and put ice in it. Also the towel at the party was a solid beige towel, and the one Ty shows Cher has a green floral design on it.
