Help me to prove something to a friend!

At the weekend a girl showed a clip on her mobile / cell phone to a mate with a monkey doing its laughing noises and waving its arms. There was a flash of colours in it too. What I need to show him is that the colours were actually text saying "I want you"! I know this because I have seen this before but can't remember where.

He thinks I am making this up, so please help me to prove this by posting a link to this clip on here. I have searched and searched but cannot find it. If anyone can find this clip I will massively appreciate it.

Cheers! :helpsmili
