Filipino and Jewish culture

Sometimes I find it amusing that we Filipinos we circumcise our boys. When we men go for a drink with our buddies specially when we do it in someones place, we use 1 cup for everyone to drink from. Is it possible that we are one of the lost tribe of Israel ? Just asking a question, maybe I should have my DNA looked at. That would be big news if it turned out that indeed we are one of the lost tribe.
