The only one I can think of off the top of my head is that one for Sinecort (or whatever) where the freaky mom and daughter are lying on their backs saying "I love you"..."I love you more". Mom's love is superior because she gives her kid some medication that European women have been giving their children for years. I refuse to buy that product simply because zombie mom and zombie daughter give me the creeps.
I know it's not supposed to be funny, but that commercial totally reminds me of the Little Britain USA commercials with the Ellie Grace character. I'm waiting for the kid to say "I love you more than interracial gang bangs"!
Another funny thing they do with the products is have some British guy hawking them, especially on Infomercials.
But you can't talk about "foreign products" without mentioning Ginsu knives! They started the whole infomercial craze and I think they were the first to use the phrase "But wait, there's more" in a commercial. I found out that them shits are made in Ohio. So much for ancient Samurai secret!
