When Sal and Q are pitching their toys to the focus group, Q's Sister Track kit is visible (obviously on desk) in the bottom right hand corner of screen just before Sal plays the promotional video of his presented toy. After Sal completes his toy pitch he tells the group "you haven't seen his toy yet. Q pulls a box from the floor and pulls out the sister tracker kit after it was already visible completely out of the box.
Sal says that he's purple belt in Taekwondo. There is no purple belt in Taekwondo.
