Bananas in pajamas are coming down the stairs,
Bananas in pajamas are coming down in pairs,
Bananas in pajamas are chasing teddy bears,
'cos on Tuesdays they all try to catch them unawares!

The song became so popular that they based a children's show on it. It premiered July 20, 1992 on ABC. The spelling was changed from 'pyjamas' to 'pajamas' to reflect the American pronunciation of the word.
They released an album in 1997, called Bumping and A Jumping. The show was retooled and revived as an all-CGI cartoon in 2011.
