I have in the past been known as ‘spirit-level Dave’ due in no small part to my ability to dance very enthusiastically through a whole live set of almost any music genre without spilling a drop (except past my lips) of my pint..
I dunno if I can still do it.. probably not..
All sorts of gymnastic style “stunts” like freestanding handstand press ups.
I’ve seen my little brother do press-ups in the normal press-up position but with his toes hovering six inches from the floor.. quite impressive.. he never used to show off about it either! He can’t do it any more though due to heavy cider swilling darts training..
