Mistaken Identity

"Ok pops, What part of us looks like street performers?"

I was in a chat sometime ago with a girl and she told me:

Girl: I bet You are a CPA (Certified Public Accountant).
Me: Sorry, Im not. Im an Engineer.
Girl: Ohh true.
You have the look!
Me: Wha...? Do I have a look??

There are sometimes I would like to answer just like Ed!!

Have you been in some sort of mistaken identity??
