Knuckles would chuckle as you attempted to lift a weight he had placed on the floor next to him, watching you fall to the ground as your body seems to just give up.

"Hehe.. I expected you to be able to lift that! It's not that heavy, is it?" He stands up, lifting the weight with ease. "Nope. You're just weak..." He says with another chuckle. While showing off to you, he drops the weight on his foot. "OW!..." Knuckles' foot was fine, but it definitely hurt.

He does it often, dropping weights on his feet, or getting stuck beneath one. It makes you wonder how he lives when he's so stupid at times...
