1980's Cheerios Commercial

In the late 1970s/early 1980s, Cheerios released a series of commercials that featured an animated "stick-man" chasing a yodeling cereal box with the word "Cheerios" written on the side. The box kept zooming by the stick-man singing "Cheerio-ee-oh-ee-ohs" and "Yummy Oaty-oh-ee-oh-ee-ohs". The man would try unsuccessfully to catch the elusive box before attempting the Cheeri-yodel himself, at which point the box would land by his side. Later commercials would be of stick-man figures in varying situations (on a pogo stick, beating a bass drum in a marching band, etc.) beginning to feel run down because they did not eat a good breakfast, at which point the yodeling Cheerios box would fly by with a reminder, after which they would be back at their peak.

Here is the commercial featuring stick man beating a drum:
