A poor little mouse walks into a bar one day..all sad. The bartender (a bear) asks why the long face? the mouse tells him that he is very lonely. "well" the barkeep says..."you can hook up with Shirly...she's the giraffe over there in the corner...send her a drink and she's all yours!" Well, a drink is brought over to the giraffe...she smiles back at the mouse and the two eventually walk out together.
Next day about the same time the Mouse walks back into the bar...all tired, dragging itself up to the bar. The barkeep asks "What the hell happened? did a truck run over you?... You look like crap!
The mouse says " No no no...I'm ok...had a great time with the Giraffe...but between the kissing and the making love ....I must have ran a hundred miles!!!
