Little Johhny

Little Johnny keeps asking his dad for a television in his bedroom, but his parents keep refusing to buy him one.
After months of nagging, his father agrees to buy a telly for his room, to shut him up.
Several night later Johnny comes downstairs from his bedroom and asks, "Dad, what's Love,Juice?''.
Dad is horrified, and after looking at mum, who's also gob smacked, he procedes to tell his son the whole facts of life, warts and all.
Johnny now sits on the sofa with his mouth open in amazement.
Dad asks, "So, what is it you've been watching on TV son?".
Johnny replies, "Wimbledon!!".:D
