 The teddy bear that Radu finds in  _"Space Cases" (1996) {Who Goes Where (#1.2)}_ (qv) is the very same  one that Sheridan tosses out of an airlock into space in this  episode, which was written by Space Cases creator  Peter David (I) (qv). Its a running gag between David and Babylon  5 creator J. Michael Straczynski (qv). Davids wife gave the bear  to JMS, who hates "cute" things, and thus had Sheridan dispose of it  in a rather unkind manner. Peter David took revenge in defense of  his wifes honor. When Radu brings in the bear, Rosie says, "What  kind of dope would toss a perfectly good Earth bear into space?"  Later, we find out that the bear was left by an evil race called the  "Straczyn." JMS has reportedly sworn vengeance.
