Just in case you still don't get how to draw a grumpy old man:
First, draw a j. -我的名字叫
Then when it comes to the part "我有两个眼睛", draw 2 eyes.
Then when it comes to "我三天没吃饭", write a chinese 3 on top.
Then when it comes to "四天没喝水", write a chinese4 on top.
When it comes to "走过全世界", draw a circle outside.
& when it's "我有两个老婆", draw 2 ears for him.
Then "三个孩子", draw 3 strands of hair.
And when it's "他们叫我爸爸", draw 2 big curvy lines for the moustache, just like the same as the top of the word 爸.
There you have it, a grumpy old man, just like you! 8D
