His finger became stuck with those little teeth digging in and his finger turning a nice shade of blue. He was panicked, but in that calm sort of way: "My finger is really stuck" "What am I going to do" "It hurts and I can get this thing off"..... But trying not to really freak out (read: Swear - a lot) in front of the girls.
I used a butter knife to pry the prongs out of his finger, however the lid would still not come off.
Luckily, on a whim, I picked up this little gadget the day before at Wal Mart:
Finger saved. Phew. Best $8.49 ever spent if you ask Hubbs.
(as a bonus it also includes a tiny screwdriver for those common every day things - battery covers anyone - and a small retractable blade!)
