The sun's been shining in Dublin lately

Turns out the bit of sun that Ireland has been basking in lately has truly made some people a little nutty.

This video, posted on The Journal, shows some revelers perilously jumping from a Dublin restaurant rooftop into the Liffey River - which was some distance away.

Mad from sun stroke, perhaps? If you can't take the heat ... maybe go find some shade and air conditioning before you consider jumping into the Liffey.
