Both those quotes were actually from Dustin.
and the rap was from Kiev, Ukraine.
It goes something like this.
"We're in a race around the world and we're here to say, we are from the USA!"
"Kuwait heat and we carried some bags, by the time it was over we looked like hags!"
"Madagascar & Mauritius we were number 1, they were havin fun in the sun!"
"Then there was Finland where we cracked some limestone, all I heard her say was 'Moan, moan, moan' "
"Finally Ukraine, where we ended this rap, give us a hand and we'll stop our spat" (I think)
Then after they received the clue, Dustin rapped "Thanks for the clue and you have a great day!"
