Best one I seen was years ago in pub, couple boys taking the piss out of a few teenage travellers …
Was old boozer with bar , lounge and games room with pool table, darts jukebox etc.
One of travellers said to lad “have you ever been hypnotised by a gypsy?” Lad looked a bit confused and replied “naaa never “, Traveller said “Great mush, you just close your eyes, I guaranty you will wake up seeing stars”. Lad closed his eyes and got head-butted square on the nose, dropped to the floor holding his bust nose…
Travellers laughed and told his pal to take him home so they could get on
