As mad as a box of frogs

If you put me in a box I'd be pretty mad (after about an hour or so).

Found this nice picture, but when I see it, I've got the phrase 'a frog in the hand is worth two in the bush' in my head. I know it's bird (shut up).

Nailing jelly to a wall

I've never done it, but I think it would be fun.

I'll eat pretty much any flavour jelly you put in front of me.
Sucking jelly through a straw takes skill and ability but once there you get an immense sense of achievement, that cannot be put into words. I'd recommend it to everyone.
