ALLLOOO!

This was a few weeks ago:

We were sitting watching TV and we heard someone outside screaming... "ALLLLOOOO .....ALLLOOOO .......ALLO?"

I'm not sure who he was hollaring to or at, but he kept going:
"ALLO? ...ALLLLLOOOO .....ALLLOOO"

We turned the TV off and listened,
"ALLLOOO .....ALLLOOO ....ALLLOOOO"

We went out on the patio to look around and see if we could see him:
"ALLLLOOO ....ALLLOOOO .....ALLLLOOOO"

It is still a mystery!

"ALLO?"

And we laugh about it everyday when out of nowhere someone says "ALLLOOO"!
