One Little Ship
(Picture is of Dax in a little-tiny ship with a normal size Worf looking in)
Thanks to a strange nebula Dax, Bashir, and O'Brien get shrunk down to a TINY size and then Jem'Hadar take over the Defiant and all sort of interesting things happen. There is a cute scene where Dax and Worf discuss Worf's poetry (which is very corny) as well as a scene where a tiny Dax runs into a HUGE (actually-normal sized) Worf. :-) Fun, fun, fun!
