Chip and Dale actually had 2 sets of actors voice them in the short “Two Chips And A Miss”. The singing voices were done by two ladies, I guess so they don’t have to distort the voices as much.

At the end, the two try to kiss the girl, to which she ducks, and I just had to make an icon of this comedic shot which you can use wherever you want:
