Spike Milligan had some good ones:


I must go down to the sea again,
To the lonely sea and the sky;
I left my shoes and socks there -
I wonder if they're dry?


Said Hamlet to Ophelia,
I'll draw a sketch of thee,
What kind of pencil shall I use?
2B or not 2B?


There are holes in the sky
Where the rain gets in
But they're ever so small
That's why the rain is thin.


On the Ning Nang Nong
Where the Cows go Bong!
And the Monkeys all say Boo!
Theres a Nang Nong Ning
Where the trees go Ping!
And the tea pots Jibber Jabber Joo
On the Nong Ning Nang
All the Mice go Clang!
And you just cant catch em when they do!
So its Ning Nang Nong!
Cows go Bong!
Nong Nang Ning!
Trees go Ping!
Nong Ning Nang!
The mice go Clang!
What a noisy place to belong,
Is the Ning Nang Ning Nang Nong!
