Jerry Nelson's great at voicing The Count Von Count. He is also great at doing Fat Blue, Sherlock Hemlock, and many more.
For The Count:
Greetings! It is I, The Count. I am called The Count because I love to count things, yes. Ah Ah Ah!
For Sherlock Hemlock:
E-Gad! Yet another mystery solved by Sherlock Hemlock the world's greatest detective.
For Fat Blue:
(Sees Grover)Oh No, it's you again!
Jerry Nelson does some of the funniest characters on Sesame Street.
