[COMIC] The original inventor of a**-eating.
First of all, I want to profusely thank Alex for helping translate Adder's dialogue to polish to really sell this joke! 
The english breaks were done by me after a little research on which sounds and words Polish and Czech may somewhat share between them, with the intention of recreating Henry's (a czech speaker) frequent struggle with understanding his comrade's mother tongue. As a native speaker of a language that has a lot of similar-sounding cousins of its own, I found that bit in the game particularly funny LOL.
Oh. Yeah and uh. Adder giving unsolicited bedding advice. As always.
Alex translations in full:
"Wsadź mu język w dupę.”/
“Put your tongue up his ass.”
"Nie pozwolisz mi zabrać tej sztuczki do grobu, co nie, Heniek? Zaufaj mi. Faceci za tym szaleją.”/
“You won’t let me take this trick to my grave, will you, Hal? Trust me. Men go crazy about it”.
"Słuchaj no, młody. Raz w życiu zachowaj się jak mężczyzna. Kochasz go? To wyliż mu zadek.”/
“Listen, lad. Act like a man for once in your life. You love him? You give his ass a good licking.”
