Followup suggestions for Pink Floyd

Some fans perhaps feel that Pink Floyd haven't really followed up their masterpiece 'The Division Bell'. This condition might have been brought about by lexical reticence, so I'd like to lend them a hand they do not need by proposing the following titles:

• The Multiplication Whistle
• The Subtraction Kazoo

Logical operators out there will be able to come up with further suggestions. Although these have taken me twelve years.
