"Santa Claus is making his" joke

Santa Claus is making his rounds, and suddenly becomes startled by a
beautiful woman gracefully walking down the stairs in a very sheer
nightgown.
"Santa Claus, will you make love to me?" she asks seductively
Santa replies" Ho, Ho, Ho, Santa's gota go... Gota deliver toys to all the
good little girls and boys."
The lady, removing her nightgown is now in a very tight and lacy teddy
and again asks:"Santa Claus, will you make love to me?"
Santa, sweating now, gains his composure and still replies "Ho, Ho, Ho,
Santa's gota go... Gota deliver toys to all the good little girls and
boys."
The beautiful woman proceeds to take off the teddy, revealing her
worderfully formed nude body and again asks: "Santa Claus, will you make
love to me?" even more seductively
Santa, can't take it anymore and replies" Hey, hey, hey, Looks like
Santa's gotta stay...there ain't now way I'm getting up the chimney this
way!"
