ingilizce hazırlık sınıflarında sık sık ödev verilen, her seferinde cümledeki bir öğenin değiştirilmesi esasına dayanan, 20-30 cümleyi alt alta sıralayıp sonlara doğru boka saran, ödev kabuslarından sadece bir tanesi.
1966 tarihli bir the who hiti, klasiği. britanya'da 5. sıraya kadar yükselmiş ve the who'nun en büyük hitlerinden biri olmuştur. buyrun sözleri:

you think we look pretty good together
you think my shoes are made of leather

but i'm a substitute for another guy
i look pretty tall but my heels are high
the simple things you see are all complicated
i look pretty young, but i'm just back-dated, yeah

substitute your lies for fact
i can see right through your plastic mac
i look all white, but my dad was black
my fine looking suit is really made out of sack

i was born with a plastic spoon in my mouth
the north side of my town faced east, and the east was facing south
and now you dare to look me in the eye
those crocodile tears are what you cry
it's a genuine problem, you won't try
to work it out at all you just pass it by, pass it by

substitute me for him
substitute my coke for gin
substitute you for my mum
at least i'll get my washing done
