A few years back, a company installed a hot tub in one of the projects.
Rumor has it, not only did TOH not pay for the installation, the spa
company paid TOH to do the job. The "selection" of the particular spa
had little to do with quality, as the spa company would like you to
believe in their ad copy.

Most of those shows are just a grout line from an infomercial.

Remember, television is a business, even PBS... NOTHING gets mentioned
by name unless it's been paid for. The most obvious examples are often
seen in racing, where different broadcasters have been known to refer to
the same event by different names, depending on how the naming rights
were sold.
