Ralph Richardson's initial put, how funny! (5,2)

I believe the answer is:
throw up
'ralph richardson's initial put how funny' is the definition.
I can't judge whether this defines the answer.
'richardson's initial put how funny' is the wordplay.
'initial' suggests taking the first letters.
'funny' indicates an anagram.
The initial letter of 'richardson' is 'r'.
'r'+'put'+'how'='rputhow'
'rputhow' with letters rearranged gives 'THROW UP'.
Can you help me to learn more?
(Other definitions for throw up that I've seen before include "Reveal" , "Be sick" , "Produce - vomit" , "Abandon (something)" , "Vomit - relinquish" .)
