Pattaya is all about jumping, but not always in the most clever way.
Bungee jumping to start with, is very popular but when you're used to Western safety rules, you might reconsider your decision to make a jump when you see the rope. They claim it is 100% safe, but I don't know. They didn't see any crocodiles in the lake where you'll be jumping, ...now that's a relief!...:-)
Another popular activity is base jumping, as this old article shows with some nice pictures. But again, I'd personally prefer to decline the offer.
Suicide by jumping in Pattaya is very popular too. It is amazing how many articles you'll find about people jumping to their death.
I'll keep it with the most popular jumping sport in Pattaya: jumping in the bed, the risks for injuries are minimal...
