Not an episode so much as one very specific street scene that's been playing over and over in my mind this morning, I believe it was from either Season 30 or 31 . . . and as I recall, Telly and Rosita were on some sort of a scavenger hunt or something, and one of the items they had to find was Ernie's rubber ducky. They brought it to Maria, who then gets a phone call from Ernie who evidently was having a panic attack and calling from his bathtub, because foam and bubbles started popping out of Maria's phone.
