And I would blip 500 more

Time flies...
I haven't planned my 500th blip well, two days in a row a bit of laziness.
However there is some thought in this:
- a bit of Scottishness;
- the are brothers here (like blipfamous brothers S, although these are not quite Scottish)
- and I know many blippers like The Proclaimers, which they've proven with more elaborate and thought out blips.

So chin chin to the next 500.
