Free Cinema
I used to do this one as a kid but it still stands up today...

If you are going to the cinema in groups of 3 or more, buy just 2 tickets, go in with one of your party, then take both ticket stubs out & hand one to another in your party.
Repeat as necessary.

*feels no guilt for passing this one on as cinema tickets are £6 these days*

unless...
... it's a full house and there aren't enough seats for everyone. Then the monkey with the torch asks to see your tickets

Or download films
for free and don't have to put up with paying an extortionate fee for entrance to a smelly cinema with someone talking in front of you and screaming kids running everywhere.
