"Concerning baptism, baptise thus: Having first rehearsed all these things, 'baptise, in the Name of the Father and of the Son and of the Holy Spirit,' in running water; but if thou hast no running water, baptise in other water, and if thou canst not in cold, then in warm. But if thou hast neither, pour water three times on the head 'in the Name of the Father, Son and Holy Spirit."
-Didache 7:1-3
Many baptize via triple aspersion (sprinkling/pouring), especially with babies, in the Old World and in Greek parishes here, from what I understand. Many also consider this an aberration.
