I thought I'd collate the whole thing to make it easier to maintain the theme.. perhaps just copy and paste with the next line..
A girl got a dog
Which did a twirl in the fog
Then tripped on a log
the log was in a bog
In the bog was a frog
that threatened to flog
the barking dog
all in a bog in prague
In the log was a synagogue
The synagogue was filled with frogs
all agog with the rabbi's prologue
then off ran the dog
cause his brain was in a fog
from drinking the grog
from the cellars of Magog.
The keeper of the grog in Magog was a cow
Who made the hoard of frogs kowtow
THANKS for the idea.
Now that 5 more couplets have been added,
I will try compiling...
