Organizing my Paper Question

[RobertJohn]

This might be lifetardish, but I'm gonna throw it out there.

When a professor asks you to attend a concert, go to a museum, or watch a play, and write a paper on it, they often ask you to provide proof that you went (i.e. a ticket stub).

My professor didn't mention anything, but I am assuming I should just staple my ticket stub onto my paper.

Is the proper convention to staple it on the front or back?

Holler.
