Herbal Essences

"Mum, when you go shopping could you get me a bottle of that Herbal Essences shampoo?"
"Any particular type?"
"Nope, apparently you get a climax with all of them."
"What!"
"You haven't seen the TV advert then, Mum?"
"No."
"Yeah, the model is washing her hair while tossing her head around uncontrollably and moaning as if she's flicking her bean."
"Flicking her bean!"
"Yeah, two quid for a shampoo that gives you an orgasm - that's a big bang for your bucks, Mum."
"And what if it doesn't work?"
"I guess I'll just have to go back to non-orgasmic Vosene."
