Bill Hader created several memorable characters during his run on SNL; Stefan, Vinny Vedecci, DJ Frontal Assault. One of his more memorable characters that only appeared once was Anthony Peter Coleman and his Vietnam Vet puppet Tony. The sketch that had Anthony Peter Coleman recounting horrible Vietnam flashbacks in a puppet class led by Seth MacFarlane became one of the show's most original sketches in recent history. 

For his first SNL hosting gig last night, Hader brought back the psychotic puppet and his flamethrower flashbacks.
