I think they should have kept Kari on and encouraged her to wear bikinis, but even without her the explosions were brilliant! But I guess there is no show that can go on forever (except the Simpsons, and I'm not sure why that is still on)!
Perhaps they could have gotten a few more years if the had recruited "myth girls" from the website below! I'd watch hot bikini girls blow stuff up any day! Hot bikini girls + explosions = brilliant!

Those boobs are awesome! They should make a show called bra busters
