Yea the little bastards can create quite a seal for themselves. I usually just pull on it slightly with a fingernail and work my way around to break its seal and then wiggle it off. Failing that I run it under hot water to soften up the plastic. Luckily there are a few DIY projects you can use a broken racking cane for.
