Translation:Sometimes, I want to marry my customers.
definitely weird. not just one customer, but the suggested answer says customers. eh boy, what kind of business are you running buddy.....
I think the sentence is testing if you recognize the difference between "cười" = smile/laugh and "cưới" = marriage. If you are not familiar with the intonation marks, you are stumped.
Plus the sentence is funny!
it always depends on the person who says it. If it's a cute girl, it's suddenly not creepy anymore :D
LoL, cute girl... Overly attached girlfriend can be cute by appearance too :P
