As I have stated in other threads Nicky has only ever yodeled twice in 11 years. Last night he yodeled for the third time ever. Why did he yodel, you might ask.
Last night Nicky yodeled because he wanted his son Clark to stop playing with Rio and play with him! He became so frustrated that Clark did not notice his play bow, did not notice his tail wiggle, did not notice him jumping all over the place that he finally resorted to yodeling. What did he get for his efforts? He got leaped on and wrestled with, exactly what he wanted.
