Look, it doesn't matter why, but the fact is that you're stark naked, in the buff so to speak, and you're in a shopping centre and you've got to get back all your clothes PDQ.
Bulldog has gone mad, and I'm talking mad. Streaker is an arcade-adventure, involving a quite hideous fat, naked sprite (who for some reason is still wearing his shoes).
The usual controls are here: Pick up, Drop, Examine and so on. The game can be played using the keyboard or a joystick. Not that it matters - gameplay is terribly trundley and not very entertaining.
