 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  _"Babylon 5" (1994) {There All the Honor Lies (#2.14)}_ (qv), 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.
