REX. Knocking back quailified pilots
Nothing too mysterious in this!
You ever seen a
quail fly?
Lots of furious fluttering before a gradual descent into the scrub.
Not really what REX are looking for, IMHO!

Good one Doc, except I think they all missed it. Wasted on them.....
Maybe that's why Rex knocks them back......

Just kidding guys, spelling and subtle gags are not prerequisites I am sure!
