at the promise of a punch-up
ar yr addewid o sgarmes

i will throw a few more quotations at you :
dyfynnaf ychydig mwy o'r adroddiad ichi :

i could throw a mountain of statistics at you , andrew
mae pentwr o ystadegau y gallwn eu taflu atoch , andrew

that was a good attempt at a punch line , but it fell noticeably flat
yr oedd yn ymdrech dda ar ergyd , ond roedd yn fethiant amlwg

a detection system is in place , whereby samples are taken , but it is impossible to test every potato that is imported , in the same way that it is impossible to throw a cordon around the uk and keep it free of disease
mae system ganfod ar waith , lle y cymerir samplau , ond mae'n amhosibl profi pob taten a fewnforir , yn yr un ffordd ag y mae'n amhosibl gosod cylch o amgylch y du a'i chadw yn rhydd o glefydau

people think that it will be great to go there and that maybe there will be , if not a punch-up , some interesting goings on -- stand-offs between police and local youths or whatever
mae pobl yn tybio y bydd yn hwyl mynd yno ac efallai , er na fydd ysgarmes o bosibl , y bydd rhai digwyddiadau diddorol -- ymrafael rhwng yr heddlu a llanciau lleol neu beth bynnag
