For future reference, a really nice guide on how to build indicators for Gnome3: http://candidtim.github.io/appindicator/2014/09/13/ubuntu-appindicator-step-by-step.html

Complete source code:

import signal
import json

from urllib2 import Request, urlopen, URLError

from gi.repository import Gtk as gtk
from gi.repository import AppIndicator3 as appindicator
from gi.repository import Notify as notify


APPINDICATOR_ID = 'myappindicator'

def main():
    indicator = appindicator.Indicator.new(APPINDICATOR_ID, 'sample_icon.svg', appindicator.IndicatorCategory.SYSTEM_SERVICES)
    indicator.set_status(appindicator.IndicatorStatus.ACTIVE)
    indicator.set_menu(build_menu())
    notify.init(APPINDICATOR_ID)
    gtk.main()

def build_menu():
    menu = gtk.Menu()
    item_joke = gtk.MenuItem('Joke')
    item_joke.connect('activate', joke)
    menu.append(item_joke)
    item_quit = gtk.MenuItem('Quit')
    item_quit.connect('activate', quit)
    menu.append(item_quit)
    menu.show_all()
    return menu

def fetch_joke():
    request = Request('http://api.icndb.com/jokes/random?limitTo=[nerdy]')
    response = urlopen(request)
    joke = json.loads(response.read())['value']['joke']
    return joke

def joke(_):
    notify.Notification.new("Joke", fetch_joke(), None).show()

def quit(_):
    notify.uninit()
    gtk.main_quit()

if __name__ == "__main__":
    signal.signal(signal.SIGINT, signal.SIG_DFL)
    main()
