Pavlov was a psychologist, I think Who supplied his dogs with food and drink But always preceded the giving of the victuals By ringing a bell, that was his ritual
The dogs became conditioned and would begin salivating Upon hearing the bell, which to the food they were relating Their mind was programmed by this little tinkle Though they didn't realise it, they had no inkle
The noise of a bell, though it didn't taste or smell like food Got these dogs in a very hungry mood Just like smokers are conditioned to relax and unwind By inhaling noxious fumes which only confuse their mind
