I think that some respondents may have confused the band Deez Nuts with the bad joke that hijacks other things in order to set up the opportunity to say "deez/these nuts", due to their similar names.
Furthermore, some respondents may have confused both of these with various quantities of various types of nuts they may have been actively or then recently eating.
That said, these effects are probably relatively small, especially in comparison to the effect of being asked a question out of left field and having nothing to say, apparently.
