Here's what you need to construct a fake monster penis.

Here's what you need to construct a monster penis and balls (what I used at least)

1) A can of hair removal cream, I use Veet by the way.

2) A thin, small plastic bag (as shown in picture)

3) Two tangerines.

Put them together, you should have the following effect, Voila!

Goofing around is so much fun!
