In the past, TTVDB has been known to be extremely slow at certain times 
of the day and week due to heavy load, primarily from XBMC users.  I 
assumed this is what was going on in this instance.  Considering instead 
this is a persistent issue involving a single show, I checked it out to 
see if maybe this is something that should be flagged upstream.  
Instead, this seems to be a problem with the grabber itself, as it 
immediately hit 100% CPU usage, and sustained that until I manually 
killed it.

My guess is that it's trying to pull the entire series and process it 
all at once, before returning the desired episode.  Most shows only have 
a few dozen or maybe a hundred or two episodes allowing fairly quick 
processing.  The Daily Show on the other hand is running into the 
thousands of episodes.  I'll take a closer look at this later and see if 
it can be improved.
