I forgot to take my shirt off this morning during my morning glory, gave myself an Irish Chimney and ralphed everywhere.

I missed lunch today. Took a deuce right before hand, gave myself an Irish Chimney and lost my apatite.

Bob called in sick this today, I wondering if he's suffering from an Irish Chimney.

-"Don't forget to close your Irish Chimney."
