Who’s your favourite grandpa?

Who’s your favourite grandpa? Not from the angle of who is best for meemaw. Just as a character, who is your favourite?

My choice might be unconventional, but it’s Dr Linkletter. He is hilarious, great sense of humour, peak sarcasm and honestly, went through the most bs with Sheldon. Dr Grant, I’m on your team all the way! Also, loved the scene when he got all candid about why he never married…
