In the New Adventures of Superman, there was an episode where Superman, in his Clark persona, ate a lot of m&ms very quickly. I think he and others were infected or under the influence of something, causing them all to act greedy (possibly just Clark, though).
I remember the scene where Clark and another man both had a jar filled with candy (m&ms, I think). The man looked away for a second, and Clark used his super sucking power (?) to suck out all the candy from his own. When the man looked back, Clark's jar was empty, with Clark was chewing on the last bits in his mouth. The man then turned away, protecting his jar.
Can anyone help me find the episode with this scene?
