I'll try to improve that translation a bit -
"Nah mate, I was in a different queue, besides, I'm old enough to be her father"
The joke is a pun on "removed". ie. slightly old fashioned English usage to say "at some distance removed" or more usual meaning "forcibly removed by someone in authority position" Is it perverted to say tits, of course not, staring at young check out girls, maybe a bit
