The Cat Loves the Mouse

We've come a long way from the cave
 What, you started to shave?
 Now we know just how to behave
 Since chivalry decided to bathe
 And as the skirts we wore were increasingly high
 Till the hem was just a cloud in the sky
 And the chat up lines got increasingly fly
 As the truth bought a suit and a tie
 The cat loves the mouse
 The mouse loves the cheese
 The bees love the birds
 The birds love those bees
 The bee loves that honey
 So honey please
 Why are we so different to these?
 So when I'm old and I'm grey
 You know you already are
 When I'm overweight
 You know you already are
 If I've overstayed my welcome by a day
 Just feel free to say
 You know I already have
 And as the skirts we wore were increasingly high
 Till the hem was just a cloud in the sky
 And the chat up lines got increasingly fly
 As the truth bought a suit and a tie
 The cat chases bird
 To the top of the tree
 The dog chases postman
 To the end of the street
 The postman he chases
 Every girl that he meets
 So why are we so different to these?
 I've been your bird, I've been your bitch
 I've been whatever B you ever wished
 I've been your cat, I've been your chick
 I've been which ever C you thought to pick
 I've been your bat, I've been your cow
 I've been whichever B and C that you'd allow
 I've been your dog, your dragon and your duck
 I've been whatever D you thought was cool to f**k
