"The Tailor and the Mouse" (Roud 16577) is an English folk song.
The tailor thought his mouse was ill Hi diddle um come feed-al He gave him part of a blue pill Hi diddle um come feed-al
The tailor thought the mouse would die Hi diddle um come feed-al He baked him in an apple pie Hi diddle um come feed-al
The pie was cut, the mouse ran out Hi diddle um come feed-al The tailor chased him all about Hi diddle um come feed-al
The tailor found his mouse was dead Hi diddle um come feed-al So he bought another one in his stead Hi diddle um come feed-al
