Get the hobo espresso mug.
The cheap and effective way to wake up a hobo whilst he sleeps. One would pull down the hobos pants and slide ones tongue into the hobos anus, forcing the hobo to wake up abruptly. May also cause him to wipe the spit out of his anus with his crack/meth covered fingers, thus furthering his alertness.

This is told to work better or just as well as a normal espresso that you would buy from your local Starbucks.
"This morning I was given a hobo espresso from Tucker, thats why I'm begging for change so early.
