UH ice cream?

Clara was making an obnoxious noise and it was driving Fin crazy.  Finally, in an effort to completely distract her, he asked, "Baby?!?  What is your favorite ice cream?"  Clara stopped making the obnoxious noise and started thinking out loud, "Uhhhhh, uhhhhhh...."  Fin interrupted and said, "Your favorite ice cream is UHHH? Can you put chocolate on that?"
