What is the original song that family guy copied this from?

ok so i was watching family guy and they sang "you and i are so awfully different" and heres the link to the song http://www.youtube.com/watch?v=eUF7CMQEx... and the link to the lyrics are http://familyguy.wikia.com/wiki/You_and_...

i was was wondering if anyone knows the song this really came from so does anyone know where this came from?

i was just watching it right now and i want to know..it sounds like a famous classic...anyone know?

the episode is called "road to europe" and according to wikipedia the song brian and stewie sing to get the camel is a parody of Bob Hope and Bing Crosby鈥檚 movie "Road to Morocco." Stewie and Brian鈥檚 musical number parodies a similar number performed by Hope and Crosby in the movie...here's a link to the wikipedia article w/ this info:

It sounds VERY familiar but I just can't put my finger on it

Hahaha.. what a coincidence, I was just watching Family Guy right now, too.
SOrry, the song doens't really sound familiar.
