A man walks in to a bar, and says “G-g-gimme a b-b-beer.”

The bartender says, "Seems as though you’ve got a major stuttering problem."

The man replies, "N-n-no k-k-k-idding!"

The bartender says, "I used to stutter, but my wife cured me. One afternoon she gave me oral sex three times in a row, and I haven’t stuttered since!"

The man says, "W-w-wow, th-th-that’s great to kn-kn-know…"

A week later, the same man walks in to the bar, and says, "G-g-gimme a b-b-beer."

The bartender says, "Why didn’t you try what I told you?"

"I d-d-did!" said the man, "It j-j-just d-d-didn’t w-w-work… ….b-b-but I m-m-must say, you have a r-r-really n-n-nice apartment!"
