How About some Nicknames?

As you might well know, we've got a bit of a naming problem at the moment. We now have 3 gentlemen working on site who carry the same name : Henk. We have Henk Diederichs (he arrived first), then came Henk le Roux and believe it or not, new arrival Henk Botha. Now you must agree that it is a bit of a pain to have a conversation with someone where you have to keep on referring to whichever Henk by his first and surname (not to mention how confusing it can get on the radio channels). So come on guys - we need to give you some nicknames - Henk-1, Henk-2 and Henk-3 is just so boring. Either you come up with acceptable nicknames or we'll have to do it for you - risky, risky! Maybe Rachelle, Ilze and Mardi can suggest some suitable names? Apparently Mardi already has one for Henk-3 but he refuses to say what it is - come on - it can't be that bad (or is it that good?).
