Jerk with ambition to be comedian (3,4)

I believe the answer is:

bob hope

I'm a little stuck... Click here to teach me more about this clue!

'comedian' is the definition.
(I know that Bob Hope is a comedian)

'jerk with ambition' is the wordplay.
'jerk' becomes 'bob' (I've seen this in another clue).
'with ambition' becomes 'hope' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'bob'+'hope'='BOB HOPE'

'to be' acts as a link.

Can you help me to learn more?

(Another definition for bob hope that I've seen is " place of 1 8 [FLYING START]".)

I've seen this clue in The Telegraph.
