Need to find some examples of Dougal's devastating insights to illustrate this...
For example, Dougal and Ted visit a tourist attraction and see a map poster with the legend "You Are Here". Dougal exclaims "Wow! How did they know that?"
In another scene Ted compares some toy cows with the real cows in a nearby field: "Now, let's try it again, Dougal: these are small, but those are far away. Small...far away. Small...far away." Dougal shakes his head in amiable incomprehension.
Ted: "Dougal, I have some good news."
Dougal: "You're getting married!?"
Ted: (pause) "You were joking there, weren't you?"
Dougal: "Er, yes."
(You may remember that Catholic priests are required to practice celibacy.)
