From Homestar Runner Wiki
One of the ultimate mysteries of the series is that
Homestar Runner,
Marzipan,
The King of Town and
Homsar, as well as many other characters, all
lack visible arms and hands. In spite of this obvious handicap, they have the ability to pick things up and carry them around. The most common explanations for the phenomenon are that they either have invisible arms or can manipulate objects with some kind of
psychokinesis. Usually none of the other characters seem to pay attention to this curiosity, although sometimes their lack of hands is referenced.
