"Taking delivery of a brand new outdoor swimming pool, a builder films
as a crane operator attempts to hoist the ready-made structure over the
new owner's house and into the garden." "...the man behind the lens
can be heard to exclaim "watch out for the chimney" as the delicate
operation progresses."
