Smoking scenes in a cartoon film might not as funny as it seems. It might get on some people's nerves.
I've read this article in Yahoo!News:
"Media regulator Ofcom received a complaint from a viewer who took offence at two episodes involving smoking..."
I personally think that Tom & Jerry is not suitable for under-15 kids.
However, another excerpts from this articles
"...Ofcom noted "concerns that smoking on television may normalize smoking," and said that the Turner company, licensee for Boomerang which aired the cartoons, had agreed to edit some smoking scenes out of Tom and Jerry."
No smoking zone getting on a rise especially in airwaves;)
Foot note: I tried searchin' for 'Texas Tom' video clip from YouTube.com. It seemed that the video had been removed by user.
