recycling random characters
 

Are those characters that were used in Bone: The Great Cow Race (the random characters Telltale made) going to be used in the next Sam and Max episode? And is the Telltale team also going to use characters from Telltale Texas Hold'em in the same manner?

We already "recycled" a few Bone characters in Culture Shock... did you spot them? :D

well let's see...
the possum on the calendar and that one guy I see from The Great Cow Race. Noticed his silhouette in Sam's Psychological bit with Sybil, and saw his face in TV in the end of the episode

Yup.

There's one more that I know of, but I don't know if anyone would be able to tell. :D

Also the silhouette and the guy on the TV are not necessarily intended to be the same person, but the same model was used for both.
