Maybe it's just late, but this is cracking me up. I was reading
this page, and I came across the following sample of what might happen if the Doctor appeared on Babylon 5:
Kosh: "Who are you?"
Doctor: "Exactly!"
K: "Who are you?"
D: "Indeed!"
K: "Who are you?"
D: "Right again!"
K: "Who are you?"
D: "Have we met?"
K: "Who--ah, screw it!"
HEE.
ETA: Also, the Chekov/Bester one! BWAHAHAHAHA!
