Best way to monetize this traffic

Hey ppl,

I found a quick method grab some good traffic.. Now I'm monetizing it with selling "funny t-shirts".

Here are the stats so far:

Clicks: 2700
Sales: 24
Money made: 63$

Is there any better way to monetize the traffic? Maybe with a "fun" offer cause the traffic source is a "fun" place :).

Note that those who clicked (2700) knew they are going to buy t-shirts (so 100% targeted)...
