A texter asked Bluebird and Keri Belle the origin of "apo sa tuhod" (aka great grandchild) and why it was called as such.

Left scratching their heads, the two dug deep in their subconscious (aka the internet) and scrambled to find out the real answer!

Listen to what they found out (or made up)!

There's zero tolerance for not answering any kind of question during the TAG Gising Na Radio Show because these two will give everything they've got give you the answer (or at least try to come up with something you can live by)! Tune in from Sundays to Thursdays, 5AM to 10AM only on TAG 91.1!
