I wonder if these were the same hotdog puppets the Henson company used in the short lived Saturday morning show, "Kid City" which ran in the mid 90's on ABC. Actually, I think that's what it was called. It was something "City." Anyway, they had these little bits where we'd see the life of a hotdog inside a hotdog vender's cart, and these little hotdogs were all rappers, led by Franky Frank and the Furters. They'd do a rap, then one of the hotdogs is plucked out of the steamer by a giant pair of tongs. That always cracked me up. Anyway, my point is, I love how Puppet Up reuses discarded characters from other productions and breathes new life into them through improv. Very cool.
