Collector – donate to cancer research? *shakes bucket*

Passerby – Sure

Collector – donate to cancer research? *shakes bucket*

Scientist – Uh, no

Collector – sorry? Cancer research is a really prominent, worthy cause in today’s society, you’ll be helping to fund a better future for all humanity, for your children...

Scientist – oh, I understand; it’s just that my quandary is this – I work in cancer research – I’m a cancer researcher *to audience* thank you *back to collector*. Any money I donate in here *shakes bucket from handle* really just goes to fund my research, my salary and, more importantly *takes the bucket* my lunch!

Collector – what? Hey, come back here!
