A a non-techie goes to a computer convention...

While browsing the computers, some people started laughing at him.

"What are you laughing at!?" He asks.

"You don't know a single thing about computers!" They reply.

He gets flustered and leaves. About half an hour later he comes back with some tools and supplies.

"What are you doing!?" They ask.

"Installing Windows!" He replies.
