At the 1:31 mark in the episode, you can see '555' and 'SHOE' written on the bottom of his left and right shoe, respectively. This is from an earlier episode in the season when Steve loaned AL money to become 'The Shoe Doctor,' and start a call line for shoe-related questions. "Can I help? Shoe-betcha!"
