Now, when you picked up, were you on speaker phone and could you over hear bunch of voices before somebody actually spoke to you and said "Who are you? Can I speak to your parents?" I get this all the bloody times. Telemarketers. Fri night 8pm, cheeky rude buggers.

My husband used to give regularly to the state troopers, police, firemen etc over the phone Now I take the money directly to the local station, however they phone continuously and are very persistent.

It is always the same guy. This time, when he phoned back, my husband asked who was speaking, the caller this time tried saying ' it's Abdullah' (husband has a Middle-Eastern name) My husband started laughing asked 'Abdullah?'and then said 'Well this is Jim speaking' the caller hung up.

I have had callers ( we're in the US) laughing at my fake British accent until it dawns on them I am British. We used to get a lot of crank calls, some we have had to trace.

a few weeks ago, we had several missed calls from an italian number while we were at work. so on a saturday morning (well, technically it was not morning but i had jus woken up) the same number calls and i pick up

- hello?
- yes hello, i'm mr.... and i'm calling from company ....that makes bio products blablaba
- sorry we are not interested
- you are not interested? but we blalblabla
- no we are not interested. besides, it is saturday and you shouldn't be calling people's homes on a saturday
- ah ok. i'll call tomorrow then?

Every day I get calls with anonymous number. Theres never anybody on the line. Apparently advertising companies make bulk calls. Telephone spam! And I hate those people who call from Germany trying to sell you something.

If an incoming call shows an unknown/out of area/irregular type/withheld number, there's a strong chance I wont even answer it. If I have made a mistake and it is a genuine call, they will normally call back.
If I do answer, and they don't know who they've called (i.e. use my name), or talk to me in any language other than German (which is the language of my location), then I am very short (interpret verging towards rude) with them, if this is a cold, unsolicited call. If they are Swiss, even trained in telesales, this will be a shock to them, and the call often ends here.
If in doubt, I always respond in English. Even if they are able to speak English back, I now have the upper hand, as I have to assume that my knowledge of the language will, in nearly all cases, be greater than theirs, and now I have also dictated in which language the conversation will continue, therefore control has shifted to me.
Finally, if I am at a loose end and have a bit of time to spare, or a bit bored, I ask if they have discovered the Lord Jehovah, in their life. Usually does the trick.

The best one I had was an SMS from some poor guy who thanked me for the wonderful weekend we had just spent together and that he had kept two of my pubic hairs in his wallet as souvenirs.

I replied saying that she must have given him a wrong number.

He replied that he didn't care - he had had a great weekend anyway....!!!

How did he get them, whilst brushing his teeth?

That's a very strange pick up line I tell ya. I wonder how many messages that poor sod sent.

Now, are you sure you just didn't have amnesia?

I was selling a house, placed an ad, didn't specify the exact address.
A fairly old guy calls and asks for the exact address.
I reply telling the guy who I was, I add that I need his name before providing that info.
He replies that it is none of my business.
To what I reply, that it is.
He tells me to f... myself and hangs the phone.
This chap was still in the analogue era. I had his number in my digital phone.
I did a reverse search and got his name.
I called him back, he picked the phone.
"Mr. XYZ: you are a mature person, you should not say things that would embarrass you if people know you by name, phone and address".
He groaned a little bit and hanged up again.

This only works if it's a landline

The wrong number can hide the right guy!!!
