Huh, I'm surprised nobody has suggested this. Just block one hole (The bowl most likely), blow into one hole (the part where you normally inhale I'd assume) and get the bud to pop through the carb. Since it's been sitting in water for who knows how long it's gotta be pretty saturated, which means you should be able to get it to block the carb and then pop out via air pressure. I dunno though, give it a shot if you want.
...unless the inhale hole is bigger than the carb. Good luck!
