Christopher Wein appeared on Sesame Street as a young boy in the late 1970s, interacting with Grover and Herry Monster in "Muppet & Kid Moments" segments. Wein is "interviewed" by Grover in the 1978 special Christmas Eve on Sesame Street about how Santa Claus comes down the chimney. "Easy," Wein laughs. "He comes down with reindeers!"
