I might be a white cocka-two.
Feeling caged, I try to brake free, from the 19th to the 21st: two seconds.
Only one thing on my mind, not two; stupid line between me and my cage too:
Break us into ...!
Lots of references to
the "Two" throughout the rhyme; the last line in particular (after the last edit) basically giving the title outright.
Early in the video we see
a white bird (might be a cockatoo? dubious; I think this is OP having fun), in a cage (feeling caged). The woman in the video drops the birdcage and, from 00:19 to 00:21 in the video the bird, ostensibly escaping its cage and flying off (braking[sic] free), is actually clearly tied to its cage by a string (stupid line...cage).
