Prescription drugs and side effects.
A woman asks her husband at breakfast time, " would you like some bacon and eggs, a slice of toast and maybe a cuppa?" He says " No thanks, I am not at all hungry, it's this Viagra, it has really knocked the edge off my appetite".
At lunchtime she asks him if he would like something, " what about some soup or a sandwich". He declines saying " This Viagra, really is playing havoc with my desire for food"
At dinner time she asks if he would like anything to eat. "What about some steak and chips or chicken and salad?" Once again he declines, " No thanks, it is this Viagra, I still don't feel hungry".
"Well", she says, "would you mind letting me up, I am starving"
