33377 Večerníček           Discovered 1999 Feb. 12 by P. Pravec at Ondřejov.
Večerníček is an animated figure accompanied by music. It invites children to the Czech Television to see a bedtime story every evening. Ingeniously painted by R. Pilař, voiced by M. Citavý, and with the tune composed by L. Simon, it has become a real phenomenon loved by most Czech children since 1965.
