The SAUSAGES comedy trick

The entertainer explains that SAUSAGES is an extraordinary word. He/she then goes into an amusing routine by manipulating the individual letters to create many shorter words, some of which are incorrectly spelt but nevertheless understandable. Examples are sausages are made out of SAGE, and if you can’t put them on a plate; you can put them on a SAUSA [saucer]. There are also typewritten instructions which give patter for fifteen words. On the reverse side of the letter plaques is the word LOUSY, but it is not clear what part this plays in the SAUSAGES routine.
