Dial-a-roll

You are in the lavatory. You barely made it and now you're number two-ing with unrestrained abandon, courtesy flushing of course so as not to totally offend the people who's house you are a guest in...but have you checked the paperwork situation?
Empty?!!
Frantically you search the cabinet beside you but find not a single sheet.

A few eternities worth of seconds go by in denial before you begin reviewing your options.
Option a: Yell for help, (a little drastic as a first choice), moving on.
Option b: You noticed some folded face cloths in the cabinet but you estimate your chances of successfully flushing one to be somewhere between slim and nil, (what else ya got?)
Option c: Try to ignore that squidgy, soon to be burning, sensation while you find an alternate bathroom. (not really on option is it?)

Then you remember that catchy Dial-a-roll jingle.

If you’re sittin on the loo,
thinkin your chore is almost through.
But the paper has run empty.
and you don't know what to do.
Make the caaall
