It takes him a while to understand what's going on but once grandpa realizes what's happening, his reaction is priceless! This Florida woman gave her grandad a mug that said 'you put the great in grandpa' and he had no idea what was happening.
He was so happy once he actually realized what his granddaughter was trying to tell him. He also sounds a bit like Lil Jon when he exclaims "WHAT!"
