A bloke walks into the Pub with a huge frog on his shoulder and sits at the Bar.
Quite curios, the Barmaid asks him what the frog is all about.
The bloke looks at her and quietly says, " Lady, this frog is an expert at Cunnilingus, there IS none better than him."
The Barmaid, quite enthralled by now asks if the frog is for sale or can be hired.
The bloke tells he can ONLY be hired but only works with him around in the room because the frog is shy and the fee is 20 Bucks for 20 minutes, cash up front."
The Barmaid takes the bloke and the frog into a vacant room, gets herself all prepared, the bloke puts the frog in place, minutes pass and the fog does nothing, frustrated the bloke looks angrily at the Frog and says, " Don't tell me you've forgotten what to do, already, I suppose I'll have to give you yet ANOTHER refresher course, oh well then here goes."
