I guess I'm the only one who never got to invest in Leela, if mainly because, as I've said, starting with Season 39, they moved SST on the schedule and it came on at a time I couldn't see it, and that continued up until they started doing the half-hour versions of the current season a couple of years ago.
Same with Mando, I know nothing about the guy other than his "Search for the Next Sesame Star" casting call on YouTube.
