A message to the agency behind the advertisement currently airing in the UK for Tiscali Broadband:

If you shamelessly and totally plagiarise a memorable sketch from Big Train, somebody's going to notice that you're creatively barren.
Update: Thanks to this site I found the name of the ad agency involved, so if you have strong feelings on the subject of lazy advertising slags, you might want to contact Tim Mortimer, the Managing Director of Mortimer Whittaker O'Sullivan Advertising -- his email address is tim@mwo.co.uk.
Dude. Is it possible that both Big Train and the ad agency thought independently of the same funny gag, and happened to agree on the best way in which to present it? Or that they both stole it from some prior source?
Tsk, always assuming the worst in people.
Not people, just advertisers.
