Actually, the scene if from the episode where Fred has to go back to school. Instead of picking up Barney like he was supposed to, Fred speeds by Barney. Barney runs after Fred, then has to run into work and back home, his feet read and throbbing. He is buffing them back to normal when talking to Betty. They think Fred is going to "Executive School' and Betty tickles Barney into getting him to ask his boss (Mr. Slade as well I believe) to send him to executive school as well...
