Did he pick Bilemy as a twist on Bile? Did he have a terminal condition of the gall bladder, bile ducts? IDK what else is involved in bile production or storage.
Did anyone hear him say it, or was this only on hostel registers that required a surname? BILL-uh mee, bi lee MI, even more Bellamy like The Bellamy Brothers?
Guessing, of course. Any gastroenterologists on here???
sloppy handwriting department, how about Dilema? de la mi?
YMMV LRR JMHO
