When we ask someone to give, we are helping them contemplate and deal with the growth encouraging topic of "generosity".   

It's a very good thing to wrestle with:  priorities, purpose, intention, sacrfice (love), and dealing with what the spiritual writers talk about: our "attachments".  

These are all excellent spiritual topics that we have to learn to love and to take on reguarly, hopefully in conversation with God. 

And, even better and more demanding,  when we ask someone else to go ask someone else to give, we're helping the whole chain of potential givers/askers.   Everyone can grow. 

To ask someone for money for some good cause, especially ones that one is not personally benefiting from (your slap stick example) is a great act of charity. 

We need to "raise up" our understanding of contributions to a higher and more demanding plane, eschewing slap stick or caricature thinking, which is often driven by a poor desire to demean, diminish, or get accolades from 3rd parties.
