"Ding Dong!" joke

There was a lady who was in bed with her lover one day, when she
hears a noise and realizes that her husband is home early from
work. She has no idea what to do with her lover so she sticks him
in the closet and successfully covers up every part of his body
except his balls. Thinking quick, she paints his balls red with
some spray paint.
Her husband comes up to the bedroom and opens the closet doors to
get out some clothes and notices the red balls hanging
there. "What are these?" he asks.

"Oh, those are just some Christmas Bells I picked up on sale this
afternoon," she answers.

He toys with them for a second and realizes that they are not
making noise, so he pulls them apart and clangs them together, but
all he hears is "uuuggghhh".

He says, "Honey, these things aren't working right, let me try
again." So he pulls them farther apart and bangs them together.
Still the only noise made is "UUUGGGHHH".

He is beginning to get a little annoyed and he says, "I am gonna
try once more and if these things do not chime, I am gonna throw
them in the fireplace and burn them." So he stretches them as far
apart as he can and slams them together.
At that moment, the guy sticks his head out of the closet and
screams, "DING DONG, DING DONG, DING DONG!!!!
