My previous phone number was 333-6699. All those buttons are near the right side of the phone, so little kids playing with the phone could reach them. 2 or 3 times a week I'd get a call from a 2 year old playing with the phone. At first I was irritated, but then I found it kind of amusing.

me: "hello"
<silence>
<giggling>
me: "are you playing with the phone?"
<pause>"yeah."
me: "how old are you?"
kid: "3".

Pretty funny.
