GMMTV artists who seem to be intellectually smart IRL?

Well it could be their degree program, the books they read, mad mental skills they've got or whatever observations that suggest that they're smart.

3 people enter my mind:

• Tay. I can sense some depth in him when he hosts. I remember that online show years ago where he was wearing some traditional outfit and he speaks profoundly. Well actually even in his meal date show with New, he embodies the nerd persona really well haha.
• Kay and Luke. Both had bachelor's degree in Mathematics from American universities. And mentioning them in the same breath, I remember shipping them during their early years in GMMTV coz they seem to connect well IRL.

Who are your picks?
