We've got the most raunchy Father's Day present for the father who always appears to have a few corny puns up his sleeve. Gossby's personalized mug "Worlds Best Farter I mean Father" will put a smile on his face, just like the smug smirk he makes immediately before a bad joke. It comes in two sizes: 11oz and 15oz, which will carry a large cup of coffee whenever he needs a pick-me-up. Our mugs are also suitable for drinking tea or sneaking a shot of Jack Daniel's - just don't tell the kids.
