My dad played this on the guitar for me and my family and friends...it was a favorite.

The words are:

Where do mosquitoes go
I'd like to know
In the wintertime
What do they wear
For underwear
When the wintry breezes blow
Do the young humdingers
Sharpen up their stingers
In a warmer climate
Where do mosquitoes go
I'd like to know
In the wintertime.

I can sing it but I don't have any notes...sorry
