I’m walking to work and I’d like to carry helpful things in my backpack for a big presentation. Which of these should I pack: rotary telephone, eighty inch monitor, laptop,  notepad, beer keg, pen.

The laptop, notepad, and pen might be helpful in order to retrieve and share content or take notes during the presentation. The eighty inch monitor won’t fit in a backpack, although it might be helpful if they have one at your presentation. The beer keg and rotary telephone probably won’t be necessary for a presentation.
