It is one of the episodes of King of Hill that only makes you angry rather than joyful through guffaw. I would NEVER expect some stranger, regardless of who they are, to pay $1000s for cat surgery or doctor visits (of any kind) for a cat. I wouldn't even pay such prices for people I know, much less a random pet. I have my own family to worry about, regardless of being flush with extra funds or not, because it's that very "or not" that could be the moment in which my family needs me. Of course this episode is ridiculous and the whole show's context is reliant on over-the-top ridiculousness, but, again, this only angers one rather than bringing joy because, sadly, there are people like this - gullible to fall for such ridiculousness and happily (or angrily) pays the bills of such ridiculousness, those willingly hoping to fraud others through such programs highlighted as "community outreach," and then those who are happy to call you "scum" or "trash" for not willing to pay such outrageousness billed as "community service".
The only winning grace in this whole episode is the ending with Bill - for his service, and his care and attention to taking care of a solider's pet while on duty, he is awarded a ride on a jet and given a pilot's helmet with his name on it (Bill). It was a touching ending for Bill and the audience; to see Bill finally get something good in life by those that recognize his value as a human being and as a hard worker of community outreach, especially since he truly is good and does put his all into the things he does.
