I look that bad?

I was out at the grocery about an hour ago, and my Uncle was with me. He was carrying the basket.
Standing in line, and one of the guys who stocks the shelves came over to see if I needed any help, and Uncle answered before I could.

"No, he's got me... I mean she's got me.. SHE's got me. I'm her Uncle, carrying stuff."

Me-: "Do I look that bad?"

He just sniffed giggled and popped his gum. I caught a glimpse of myself then in one of the doors of the frozen food and felt hideous.  Yeah, I'm looking like Jabba the Hut with glasses.
But I have to wonder what or who made Uncle so nervous?
