Neat Nerd Ned is a picture of a redditor, "Reddittays", farther standing in front of one of his workbenches. The caption of the image is explaining how Reddittays thought his Dad used to be a nerd but now realized that he is awesome. The image so far has been used to present electronic or engineering puns. The first captioned image other than the original appeared in a comment on the imgur page for the picture. User "Danopia" posted the link to the image which had been captioned with a quote you might hear a programmer say.
The image was uploaded to quickmeme where it currently has several entries.
