Hot Dogs in a Jar/Can

This one is for the kids.  We saw these hot dogs in jars and cans and thought the kids might find them interesting.  I would imagine they taste like longer Vienna Sausages.  In fact, that might be how the smaller American versions get their name.  I think I might have to get some before we leave to check that theory.  I like Vienna sausages.  I don't know if I want to eat more than one though.
