The Bar Once Seen A Lion

I once took a lion into an all men's bar 
At first he acted fine until the bartender asked for his card 
So this lion this damn huge beast stood up to start to roar 
But all the drunken men around were afraid to escort him to the door 
I couldn't tell you where I found him or why I took him to this place
I also couldn't tell you why he was dressed all in lace
I gotta leave it's closing time just this lion and me
And I still don't understand why they stand up while they pee
