Well here ya go
New Viagra
Tune "on Top of Old Smokey"
By Micca

On top of the sofa
with my sweetheart I lay
I popped some Viagra
To help me on my way
I dived for my true love
This new stuffs a blast
Vaulted into the garden
Its kicked in so fast

This new style Viagra
Works without delay
'stead of waiting an hour
it gives instant replay
and instant replay boys
is a boon and a crack
it gives forward momentum
but it knackers your back

so all the young ladys
are lamenting each day
for the hour of waiting
was once spent in foreplay
now their fellas are falling
back to their old way
wham bam thank you ma am
and I'll be on my way
