David Spade Auditions for TMZ Photog By Interviewing Squirrel

David Spade must be struggling, because he's apparently auditioning for the job of TMZ photog ... and he's so good he may get a callback!!!

David put his cellphone to questionable use Saturday, when he interviewed a squirrel about the pandemic. The critter was very tight-lipped -- probably because his mouth was filled with nuts. Nevertheless, David peppered it with questions ... some of them questionable.

Note to David ... it's okay to ask the squirrel about lockdowns, but asking the rodent to talk smack on Fauci -- well, that crosses the line.

David persists, but the squirrel isn't having it and scampers off into the field.
