I really want to donate...

So I was reading wikipedia (of course) and they are asking for donations (cool)...
I see the usual donate (10,20,50) dollars buttons... But the "Other" box caught my attention.
If you keep mashing numbers into the box you can get it up to "inf" dollars.
I'm going to sleep on it but I really want to charge infinite dollars to my credit card just to see what it does.
