Riboflavin

When the moon arises on the western sky
 and the vampires are out on the sly
 at times they have trouble finding necks to bite
 that's why I cook up in my roon tonight...
 My riboflavin flavored, non-carbonated, polyunsaturated blood
 (her riboflavin flavored, non-carbonated, polyunsaturated blood)
 Drac came to me one night at 12
 and said the blood bank had no blood on the shelf
 I exclaimed "don't fret!" i'll give you on fix
 of my newly regenerated mix
 I gave him riboflavin flavored, non-carbonated, polyunsaturated blood
 (she gave him riboflavin flavored, non-carbonated, polyunsaturated
 blood)
 It gives you quick relief you see
 from fang aches and corpusle deficiency
 Natter! consuming my laboratory brew
 will make a new vampire out of you
 It's that quality unleaded, only one calorie, polyunsaturated blood
 that riboflavin flavored, non-carbonated, polyunsaturated blood
 Drac enjoyed my brew without a hitch
 now he's one of those that would rather fight than switch
 if you're biting mre necks enjoying it less
 try my new non-carbonated best
 My riboflavin flavored, non-carbonated, polyunsaturated blood
 (her riboflavin flavored, non-carbonated, polyunsaturated blood
