Snow slows Santa's sled.

At my teacher training high school we learnt many tongue twisters, e.x. this one:

SALLY SPEAKS SPANISH, BUT NOT VERY WELL

Sally speaks Spanish, but not very well.
When she tries to speak Spanish,
You really can't tell
What language she's speaking
Or trying to speak
The first time I heard her,
I thought it was Greek.
