This kid I was babysitting told me a joke:
There was a guy who was crossing the border,
but the border police stopped him and said:
"You can only cross the border if you can use green, pink, and yellow in the same sentence."
So the guy said "OK" then said: (you have to say it in a kindergardner's voice)
"My phone went green green green, so I pinked it up and said 'Yellow?'"
