An epic send-up of big budget ads, featuring a cast of thousands. Song lyrics: “It’s a big ad / very big ad/ it’s a big ad we’re in./ It’s a big ad/ my God it’s big/ can’t believe how big it is/ it’s a big ad for Carlton Draught / It’s just so freaking huge! / It’s a big ad/ expensive ad! / This ad better sell some bloooooody beer.
