Bad MS Paint Meme Portrait

A crude childlike digital doodle portrait on a plain light gray background, centered and cropped from the chest up. Show a goofy adult man with a scruffy light blond beard and messy dark hair mostly covered by a ribbed gray knit beanie. Add a small orange circular badge pinned on the right side of the beanie with the white number "10" inside. He wears oversized black sunglasses with thick frames, hiding the eyes completely. His face has an exaggerated huge toothy grin with oversized square white teeth filling most of the lower face, drawn in a clumsy uneven way with a few tiny red marks at the gum line. The nose is simple and cartoonish, and one ear sticks out prominently on the left side. Dress him in a bulky black jacket over an off-white or cream sweater. Use intentionally messy, amateur, nephew-level drawing quality: jagged black outlines, rough scribbles, uneven proportions, naive anatomy, minimal shading, haphazard fill colors, and a hand-drawn MS Paint or cheap tablet sketch feel. Keep the composition simple, humorous, and slightly ugly in a charming way, like a badly drawn viral meme avatar.
